Maxamet defiled and born again.

As far as I know I have always noticed how blunt and scratched were my father, grandfather and father in law EDC folders. The old timers were using their knives hard and their blades were tools to be reliable in all situations. They were not expensive and used as screwdrivers and skinners and staples removers and whittlers and they were in contact with plates while eating with them…

Swapping the Maxamet blade on the Lightweight plateform was done for “Mule” testing  on a steel I had always babied since Eric told me it was 70HRC and since I have been waiting 9 months for getting the Para3 Maxamet.

Anyway encouraged by the Cliptools great results on opening oysters…

 

Well the maxamet lost its blade tip at the first attempt. I was able to open 4 oysters but the blade was already a mess.
On the other side the Clipitool was able to open 32 oysters with almost no damage but light scratches and edge bending. This is the kind of knife my family fathers would have chosen: thin and strong blade was always their favorite.
So really kuddos to Eric for designing the clipitoolas a reliable workhorse.

So now time to fix the Maxamet blade. And with no pity !
It means using diamonds DC4 and Double Stuff 2 to repair that edge.

Actually when you got nothing to lose, you go hard on the fixing.
Also doing that by hand will repair any factory burnt edge syndrome…

It a matter of minutes it was already going back to part serrated to plain edge.
The tip is going to take a little more time but it will be reshaped slowly.
Anyway, it is back to razor and ready to be used harder than before.

Para 3 blades swapping on New Year’s Eve

I got two Para3: a M390 Lightweight and I got a Maxamet Copper handled.
The Lightweight is so good,  I wanted to use the 70 HRC blade on that plateform.
Nothing wrong with M390 which is just a great EDC steel with stellar performances but staining steels are part of DNA.
After watching Nick Shabazz having the same idea and filming it, once the novelty of the M390 faded away, I have decided to step ahead. It was really easy to do it but for the stoppong pin of the lightweight (Torx 6) which was dismounted with two tools as it was turning inside the handle.

Easily disassembled copper scales.

Now mounted on the lightweight handle.
For more about disassembling a Para3 lightweight here is Eric Glesser’s Video.

Here we go: two excellent knives. As you can notice they are users.

I have been able to thin the edge of the M390 when the Maxamet refused to give away any particules…

The Spyder logo is golden on the M390 and black on the Maxamet.

Perfectly centered blades on both and smooth action with no lateral play.
Here my Little Red Hoodie ready for tonight 24 oysters opening.

Happy Saint Sly everyone !

Maxamet being more denser it has add 3 grams on the scales.

Spyderco C223GPDGY Para 3 Maxamet Part II.

20180508_140104-01.jpeg

The Grey Mouser has been in my EDC rotation since it has arrived in my pocket.
So this a little report.

Maxamet is like a super CPM M4 to me, it cannot seem to get dull. I have deshouldered the edge and keep it sharp (razor) with white ceramic and leather. The edge behaviour in wood is like M2, it gives a gentle patina to the part cut.

The gently rounded spine is a must for thumb push cutting.

20180508_125601-01.jpeg

The lock is solid and did not give in to any vertical or lateral play.

The Para3 is really a friendly 3 inches knife with a wide spectrum of uses.
Near the pivot you got as much as any C36 Millie strenght for power cutting as this is the same “cockpit” as the good old Military. The point is easier to control as your hand grabs the blade and the handle with more ease on smaller knives. So you got a very capable knife for the outdoors, able to carve and trim wood.

Maxamet is giving a beautiful orange red patina. I have not been able to get any pit of rust despite my every day use on acidic foods.

It’s less sensitive to medium than K390 and close to CPM10V. You got stain but nothing more in my experience.

20180610_135242.jpg

I clean it directly under the tap of in a soapy water. Nothing extravagant. The action is on the smooth side even without any oil near the pivot. I have decided to treat it the hard way.

So far I’m really impressed by the ease of keeping razor sharp that very special alloy. It’s not difficult with only white ceramic and leather and it happen once a week just for a refresh.
The deep carry clip is back for tip up carry and it makes a very low signature for an EDC.

20180602_122936.jpg

It’s used every day for eating and mostly I use the spine to push in the plate.

An apple a day keep the doctor away, especially if you got a good aim.
More to come soon but so far this is a very satisfying experience.

Spyderco C223GPDGY Para 3 Maxamet — The Grey Mouser.

20180410_132821-01.jpeg

It has been half a year of patience before my pre order turns into a mail call. Howard Korn from the Knifecenter.com was kind enough to send it to me as soon as he has received it. It was a quick 6 days of travelling from Fredericksburgh, Virginia to Paris.
The name of this Para3 should be”Desire” but it will be “Mouser” in honor of its color: grey. Also in honor of its almost magical alloy used: Maxamet.
20180410_132835-01.jpeg

What is Maxamet ?
According to Spyderco its full name is “Carpenter® steel’s Micro-Melt® Maxamet® alloy”. “Maxamet is an extremely hard high-speed powdered tool steel possessing properties that transcend conventional high-speed tool steels and approach those of cemented carbides – the ultra-hard materials used to machine other steels. When Carpenter developed this amazing alloy for the rollers in their steel mills, they sent samples to various companies in the knife industry to evaluate as a blade material. Although many tried, Spyderco was one of only a handful of companies to successfully develop the specialized methods necessary to machine, heat treat, and grind this demanding material to yield reliable, high-performance knife blades.”
It so difficult to work with that it has given some headaches to Eric and Sal hence the 6 months late in the production of that Para 3.
Maxamet should have better performance than CPM110V.  Now that I got both steel, I will try to see if I feel and see a difference.
What its composition reveals ?
Carbon 2,15% ; sulfure : 0.070% – 0,23%; chromium : 4,75% ; vanadium 6,00% ; manganese 0,30% ; silicium 0,25% ; cobalt : 10,00% ; tungsten 13,00%.

It’s not a stainless steel it’s an high tech tungsten alloy !!

Here its data sheet in Carpenter’s.

The wear resistance of Micro-Melt Maxamet alloy is better than that of conventional powder metal high speed steel grades and is equivalent to AISI A11 cold work powder metal tool steel. A11 is CPM 10V. Better? How much better ?
According to Cliff Stamps: “Maxamet is an extreme alloy, for comparison, it is to 10V what S90V is to 420J2. Maxamet is used when HSS like M4 fail because they are too soft or wear too fast – just consider that for a matter of perspective.”
(For the record he’s not talking about CPM M4 which comes from powder metallurgy process but good old M4HSS.)

So far Mouser is shaving my arm’s hairs which are flying of its blade. Its factory edge is really thin. With that amount of tungsten it should not be sensitive to its final tooling in the Golden plant. I’m not planning to work on it yet and keep it that way for its first run.

Its complex heat treatment and the HRC should be on the very high..

Spyderco is offering that steel on many knives: not counting a Mule but a LW grey Manix 2 , a G10 grey Paramillie 2 and a lightweight grey Native…
The Maxemet version is not a Sprint run.

I have also noticed the chamfered work they have made on the spine and the spyderhole and the jimping behind the hump. I don’t have to use my diamond rat tail file anymore !!
Thank you Golden ! 🙂

20180410_134623-01.jpeg
Also the blade has been gently beadblasted which gives it a very industrial look. The grind is perfectly symetrical as always on my Colorado’s made.

20180410_132849-01.jpeg
The thick grey G10 slab also concours to give that toolish look, again the attention to detail are stellar. There is nothing to change when you open your black and red box.

So far what I have changed is the clip, as I don’t plan to spyderdrop this little guy.
The smooth compression lock permits a lot of other way to open it elegantly.
Also I have sanded the G10 to smooth it to my taste and keep my pocket lips healthy.
I keep the pivot area rough for the ergos.
Now the game is on, let see all this fuzz about that Maxamet steel !
Spyderco catalog’s sheet is here.

EDIT: Eventually I have gone back to the OEM hourglass clip in a Tip Down carry option.
Because it’s so fast to draw like a I do on my Millie and Paramillie 2.
The spyderdrop is so elegant and bound to the spyderhole: it works like a breeze.
Also I have starting to test the sharpness which is uncanny right our of the box.
I did not have that kind of result with its S30V bro. The Maxamet thin edge goes through the plastic bottle butt to make tagliatelle !! The edge is really hungry.

 

Also my previous review on the Para3 is here.

 

 

Between both knives there is a little difference. It is the sound of the mechanism.
The opening and locking on the S30V version will be a TAK.
When the opening of the Maxamet version will be a TIK.
The pitch of Mouser is much higher. Different alloys, different hardness produce different sounds.

20180410_134558-01.jpeg

The Mouser is a small (not much more than five feet) mercurial thief, gifted and deadly at swordsmanship (often using a sword in one hand named “Scalpel” and a long dagger or main-gauche in the other named “Cat’s claw”), and a former wizard’s apprentice who retains some skill at magic.
The cynical-sounding Mouser is prone to showing strains of sentiment at unexpected times. He’s a rogue, living in a decadent world where to be so is a requirement of survival. It was created by Fritz Leiber.
