Spyderco C127PBN Sprint Run: First Glimpse at a Cappucino Urban Razor !

Spyderco has made a Sprint Run using AEB-L on the Urban Plateforme. Mine was bought 65 dollars with 13 dollars of shipping. An honest price and 7 days of waiting. Kudos to DLC Trading.

AEB-L is a razor’s steel. Stainless. When 52100 is also a razor’s steel non stainless (this link take you to a Jerry Stark 6/8″ Straight Razor at 275 dollars…).
Both are small carbides steels and AEB-L is a low chromium medium carbon alloy.
“AEB-L differs from most simpler stainless steels in that it forms very small carbides when heat treated and has a very fine grain structure. Since the carbides are small, they are easier to sharpen, and since the grain is so fine, edge stability and toughness get a boost. Because of these advantages, AEB-L can compete with more complex “super steels” but at a much lower cost.” says Nordsmith site who considers AEB-L perfect for the outdoors knives they made. AEB-L is also consider as a tough steel.

From Doc Dan on the Spyderco Forum:
“I have a couple of folders in 13C26 (AEB-L). It is no super steel and those who are used to S90V or something might be disappointed. It tends to bend and roll rather than chip. In fact, I have never had a chip in either knife. When we first started talking about the AEB-L Urban I was surprised to discover how tough this steel actually is. I think it is a razor blade steel, and for a pocket knife, It think it is a good choice. It sharpens easily and holds a decent edge, but maybe slightly less than 154CM, VG-10, etc. However, if it is run harder by Spyderco, then all of my experience goes out the window.”

So let’s convex it ! Gaffer tape is used to prevent any scratch on the flat of the blade.

I’m happy to use diamonds as it feels hard to scratch.
I heard it was heat treated at 62 HRC. The idea is to have it hard. It feels hard under diamonds.

I keep the factory edge and just deshoulder it.

Then some diamonds paste (thank you JD) and compound for stropping.
It get to a mirror very very fast like 52100.

It is very easy to strop it for a razor level. I have noticed also the edge is like a caress and hairs are jumping.

The point of the blade is not as recessed as on my other Urban. It due to a QC on the spring. But I cannot bring the meat of my finger to be bitten. No issue.

Now starts the test and it will be done in the UK where the Urban is a lawful folder to carry. The mechanism is quite stiff and I really enjoy that. Actually I also love its Cappucino handle and that’s will be his code name from now on.

The bottle’s butt test is passed with flying colours.

The bottle’s neck thick plastic was easy game too.

On wood, it made very clean and precise cuts.
Same feel as 52100 and the exact opposite to ATS-34 for example.
The stronger mechanism makes it much more whittling friendly.
Once the Boot’s dagger quillon held, the knife is powerful and accurate in every cut.

Pleasure of whittling — Which knife ?

A knife and a piece of wood make my day.
I can sit and enjoy a good blade taking nice wooden chips.
Steel chemistry is important, especially how fine its grain is.
Back in the 90’s I have found how a Benchmade in M2HSS was more enjoyable than the same model in ATS-34.
How is the blade is ground is also very important, scandi makes shallower cuts when hollow grind got deeper in my experience.
But more than this: the general ergonomy of the knife and especially the spine of the blade do make a difference for me.

But let’s have a look at the knives: Ed Schemp’s Tuff and Bowie, Police 4, Yojimbo 2, Sebenza, Spydiechef, PPT, Paramillie, Lil’Native, Wolfspyder, A little TOPS scandi, Mantra2, Millie and Nilakka.

A rounded spine like my Sebenza is great. It’s very thin edge is also a plus but ATS34 is not making the moment enjoyable. Of course it will cut but the pleasure of feeling how the edge is making the chips is not there. Its edge is like a mad cow !! Hard to control.

 

One of the great surprise in term of pleasure has been that Lil Blue 2 from Raker (Ray Kirk). Made of 52100 ball bearing steel and brought to razor by JD !
The rounded spine of that small fixed blade makes it super enjoyable. The fine grain 52100 makes thin chips but can also be use hard for deeper cuts. That would the kind of knife you can enjoy all an afternoon without thumb soar.

A good old Opinel N°8 is able to cut deep and with power, for sure. Do I enjoy it ? Not really. It does the job but there is no pleasure when the thin spine bites my thumb during push cuts.

A great surprise and even a better surprise that my previous whittling with a Yojimbo 2 in S90V is my Yo2 Jade with a CPM M4 blade.
It is not a knife designed for whittling but it does the job perfectly. Better even is a tougher blade in CPM M4 which is very aggressive. The spine also is thick and my thumb can push with with confort and control. The Yo2 and especially that version is a great wood companion I can use with serenity.

Another knife I highly recommend for going in the woods and whittling with pleasure. And another knife with some martial pedigree has proven to be a great whittler: the PPT.
The S90V thin blade of that edition with a very confortable handle has been eating wood like a chef.

Speaking of chef: lets’ continue with the surprises. One important side of the Spydiechef is how easily it can go out of the kitchen. Sailors and sea kayakists are using it without any risk of failure but within the woods? OK mine has been convexed but this is another great tool to bring with you everywhere. I was able to create beautiful chips and the spince have not bite my thumb. Really a nice experience with this one.

My CPM Cruewear Paramillie has been convexed and its edge was really hungry for wood.
It was in all the bunch the one which went the easiest in the rod of wood. But then the square spire was so sharp and thin: it was not enjoyable. More about it later.

The Lil’ Native with JD sharpening skill is nice and powerful for its size. Really a nice you should not judge by the size. But then again, JD reground it to almost a scandi level. The belly and the thin edge does marvel for whittling. Just a tad longer blade will improved the experience but then you got a Native not a Papoose no more.

Another knife improved by JD sharpening skill is the Mantra 2. I had rounded the spine on this one and it turned to be a very powerful wood cutter. The kind of knife which disappears in your pocket and once deployed is a game changer. The very solid construction and great ergos of that Eric Glesser design is blooming in the woods.

The Police 4, as powerful as its K390 thin convexed blade was a real disappointment. The thin spine is really hurting my thumb when push cutting. The Police is and stays a very urban design. I was not really able to enjoy fine whittling with it. It does the job but the thin spine ruined it for me. This one is much better in cutting cardboards or ropes…

Of course the Nilakka is a five stars experience. nothing new: thick spine, zero ground blade. It is powerful and accurate. Pekka Tuominen knows. Just the thin point could be an issue when digging in the wood to make a hole for example. This is were the Wolfspyder shines: a very solid point !

Another great surprise in term of pleasure has been the Gent knife from Massdrop. I had convexed the edge and its S35VN rounded spined blade is just great. Its natural belly helps a lot in term of push cuts. It is a great folder and 100% shot flipper, easy to keep clean, and look at the shape of that blade: it is stunning and for less than 100 dollars shipping included. It will be reviewed.

Sorry, but the Mora has been the worst. It was not able to bring me nice chips.
I’m certain it would be a great hard used tool in the wood but here for fine gentle whittling: zero pleasure.
The synthetic handle is becoming sticky, the scandi edge is rusting and it was not able to bite in the wood. Cheap fixed blade.

So eventually, using 400 grits sandpaper, I have decided to rounded the spine of my Paramillie 2 and of course it makes a huge difference. Actually I have been really surprise in how deep It was cutting in the wood, kind of remembering its brother in 52100.
Soon I will try AEB-L steel which is considered as a stainless 52100 on a Sprint Run Urban already in transit. So more will come.

In conclusion my more enjoyable whittler is still the Wolfspyder.
The surprise joy came for the Gent, The Yojimbo 2, the Mantra 2 and the Raker.
The Paramillie with a more rounded spine will be certainly part of the club.
The biggest down was the Police 4 and the Mora.

But in term of sitting under the porche and whittling a rod the Ray Mears designed Wolfspyder is winning. It was designed for that task.

 

Yojimbo2 vs Paramilitary2 — Face 2 Face !

20171031_131913-01430006665.jpeg

I got two requests for writing that little comparaison hence a lot of users are hesittating between those two radical designs.

My Yojimbo2 is a special edition as is my Paramillie 2. Both got carbon fiber handles. Both are made in Golden, Colorado, USA, Earth. Both are second generation.

The Yo2 has been designed by Michael Janich and The P2 by Eric and Sal Glesser. Both got compression locks and inhouse system invented by the Glesser. The Yo2 got an S90V blade and the Para got a 52100 ball bearing blade.

The steel in those exclusive runs are totally opposite. S90V is a powder metalurgy alien steel named CPM420V in the previous Century. It is like some kind chewing gum alloy which refuses to let got any particules even during sharpening when 52100 is more of traditionnal old timer bladesmith steel of choice with carbon and a pinch of chromium. S90V got carbid of vanadium and chromium and more than 2% of carbon. 52100 got 1.2% of carbon. They are on the two opposite sides of the famouse best steels spectrum. S90V will stay sharp more than 3 times longer than 52100 if used on abbrasive material like cardboard. But 52100 will be easy to reach razor sharpness. S90V loses its razor edge very fast before to keep a plateau of working edge for a very very long time.

Both knives got a convexed edge, it was a bear to obtain it on S90V.
Both got very pointy tips fir a equivalent lenght.
But the Yo2 blade is saber hollow ground when the P2 is full flat ground.

20171031_132320-01419109098.jpeg

On wood I have already noticed how great the Yo2 was for making sticks.
It has a very confortable handle for hard use and the keen edge got full power from the choil to the tip. Also the thick back helps a lot for pushing with the thumb.
Try the Yo2 on sticks: it will amazed you. But if you need some belly, the P2 will be obviously better. You won’t take the Yo2 for an hunting knife at all.

The Paramillie got this wonderful performance and control the full flat ground can provide. It is in his element: reliable and steady.
But the Self Defense knife is not the last in performing camp task. Do not underestimate it in that mattet as Michael Janich always advocated to use his knives to get used to their ergos and the way you carry them on your person.  the more you do it, the more you train to to draw them in stress situations.

20171031_132041-01501963538.jpeg

But in pure quick drawing, the Paramillie got a serious avantage: you can easily spyderdrop it. It is opened in a breeze just by drawing it by holding the hole. This is fast and actually faster than the Yo2 which required first to be clear from the pocket.
Both knives are equally smooth. The YO2 got a little more momentum because the blade is heavier. But, in my book, the Self Defense knife is beaten by the utility knife.
The Yojimbo got also more presence than the Paramillie2,  it is like one of wolverine claws and not really sheeple friendy.

So really it just a matter of look and taste if you need to choose between them.
Both a high performance folders, with great locks, great ergos and an attention to detail breed in a second generation design. Both will find a way to be very useful in everyday  chores. They are false brothers but you know…
Now, the world don’t move to the beat of just one drum,
What might be right for you, may not be right for some……
