Tuscan Raiders #4 – Geometries, Gayle Spyderco Gayle Bradley Junction and whittling.

It has all started when I wanted to review the Spyderco Gayle Bradley Junction. It’s a great design for an EDC fixed blade which can be used for everything. Easy to carry in its pancake constructed bolteron sheath. But the edge was just too thick for my own use. To my knowledge, SPF27 is some kind of CPM D2 steel. A lot of carbon 1.5% and not a lot of chromium around 12%. Not the easiest on the stone as a semi stainless. It was not very soft under the diamonds compared to another blade in N690 HRC59 I got with me. And it was not really easy to remove the shoulder to create a gentle convex edge. Patience… In sharpening is important. And I often lack of it but I was able to improve it. Next some black stone mostly to remove the scratches. And then the white ceramic to get a better finish and a razor steel. You can notice the chamfered signature hole on the Junction. A première. The cuts were deeper. It was better! Much more enjoyable. But the spine was too sharp for my thumb and diamonds came handy to rounded the angles. It would never be a Sebenza spine…. Again the control during whittling was much much better. One should never be scared to round the edges for suiting your own needs. The handle is very flat on that knife. It’s an attention for people who wish to stash their knife in a pocket or a backpack without leaving a print. But a flat knife is not the most comfortable in the palm of your hand… Especially when cutting hard things for a long time. I decided to make a quick comparison with the Spyderco Sprig which is a pleasure to use. You can notice how the Phil Wilson’s Sprig got a thicker handle. And it change everything when cutting hard things. Also Phil Wilson’s is all about performances. Its geometry is stellar. It immediately cuts deep in wood without any real improvement needed…. But diamonds were there to be usef. 🙂 I was able to get thin regular cuts into the wood. So I have decided to try the diamonds on the Gayle Bradley Bowie I have brought with me. This one got a thicker geometry and is made if the same pulverized alloy as the Junction You can always improve an edge. Used as a light chopper it worked just fine. Gayle Bradley has provided a great compact Bowie which can be used as a light camp knife. You can see: it’s not a lot bigger compared to my Ed Chempp Bowie. And the edge once thinned is honorable. Of course it is not as thin as my Pekka Tuominen Urban II for example. And not as aggressive as the Sprig… I got…. too much knives on my table…

It was time to go to lunch. An Francesca knows how to prepare the pasta with pomodori. Crostini a la Toscane. Poultry liver, oignons, red wine, bread and a Bowie. Back in the outside I was thinking of a simple way to see the “impact” of good geometry on whittling. On the right, a single cut if the thin Delica and, on the left, a single cut of the thicker ZT0562CF. The Delica cuts deeper on a more open angle. Better geometry. But the ZT was pleasant to use even if it was not as fast at the job. Also the Delica was able to cut from the ricasso to the point without any hard pressure. In the end, I had noticed that the Junction was less good than the Sprig and the Delica was still the best whittler in the batch. No matter the steel, for wood cutting, geometry is queen. So I have taken my Bowie back to the diamonds and put a keener edge. Tomorrow it will be hunting day.

  1. Great write up as always Nemo. Just a quick question in regards to scratch removal. Do you use the black stone to polish the edge, or the blade itself?
    Do you try to polish out the scratches by going perpendicular, or parallel? I noticed on the ZT review, you used the 1000 grit polish 90 degrees to the scratches, and was curious what exactly you meant.
    The black stone is just for the edge.
    For polishing not all alloys are equal.
    You cannot polish D2 or S90V.

    • CPM20V is getting a nice mirror polish.
      I have removed my scratched by doing first circular motion then motion perpendicular.
      I vary in function of the results.
      My scratches are hideous.
      Polishing is saving my blade. Just done it on my S30V Schempp Bowie.
      The edge is polished and I have decided to use the white ceramic on all the flanks of the knife. I don’t have sandpaper right now. 😊
      I will soon post pictures.

      • Thanks for the info. I tend to get some nasty scratches too. Even though all my knives are used, I guess I prefer that they come into their scratches honestly, rather than through sharpening.
