OK I just got through doing some blade clean up and here is the report
Busse FFBM THINNED AND FULLY CONVEXED to the Saber grind line by BRK&T. I think BAN will come and confirm but the general consensus is this knife was pretty easily the King chopper today. It would just BLAST through hard seasoned lumber. I chopped with it twice I know Ban did at least three sessions with it and Hogwash did at least one. There was what looked like the slightest tiny roll to the edge. But I ran a steel over it and got out the 320 grit wet dry and I was all set to set the edge just a tiny bit thicker. I made two passes on each side and what I thought were rolls were now gone totally? It was a trip. But I know what I saw and there were tiny roll spots. So I went a head and rest the very edge just a tiny bit deeper.Scotch brighted the whole blade then polished the edge out with 2000 grit wet. No evidence what so ever it got BEAT HARD.
Next We whacked a FBMLE almost the same weight and edge thickness as the FFBM convex. I don't think any of us thought it worked as well. I noticed would bind some in the wood and it just did not sink as deep. When I did clean up time it was a snap. Quick steel on the edge, a few passes of 320, 600, 1200 and the edge was fine.
ZTBM A little disappointing it did OK though. I think its just comparing it to the above knives makes it seem kind of like a weak sister. We only used it once so it cleaned up with just a few passes on the 2000 grit.
Next was a sleeper knife. OILMAN sold me Swamp rat Ratwieler at a good price because he could not get a good edge on it. I guess he sent it off to Swamp Rat and they did a very half-assed job putting a edge on it. But it was a edge. So before todays party I did a fare amount of work on it. I set the edge thinner, restored the tip and added a swedge. I had polished the edge all the way up to 2000 grit with a slight convex.
Here is the thing, it chopped pretty damn good and took no edge damage at all. Seriously none...zip Seemed to hold better than INFI. No kidding. This is a pretty darn good mid sized knife.
Next up was a Bill Buxton 10 inch camp knife he made me a year or so ago. Forged 51200. This knife has a profile that is more like a kitchen knife than a Chopper. I used it but I am in poor shape and could not generate any where near the power BAN could. Still this knife for me out cut every thing. But the blade began to fail. It was getting waves in the edge. I took it home and with some vigorous steeling I got the edge mostly straight again. Then I reset the edge and took it to burr 4 times on each side with 320 grit. This for the most part cleaned up the damage. But you can still see a few spots. This blade will never be the same. Am I upset about it yeah.. Did I learn something from it? Yeah I did.
The surprise winner and based on price point I think the Busse to buy is the CGFBM. Mine sported a thinned convex edge with very high polish. Standard scales and it chopped... real well. REALLY solid cutter. In fact it was second only to the re-worked FFBM. This is a very under rated knife.
So here is what I learned. Weight helps and so does sharpness. But geometry cuts!! There is a trade off and I bet with experience it becomes pretty predictable.
Rough handles do make knives feel more secure and less likely to rotate in your hand but this is at the EXPENSE of your hand. OOCH.
Smooth handles rotate...BAD
Properly designed handles Smoothed but designed to work with the hand are the way to go. The Buxton was the best for me.
BAN took some pictures of the knife pile...LOL and there is video of the chopping but it may not make up here..that is up to BAN.
I have to tell ya BAN and Howash have some great Knives and Ban does some world class Mods.
I sure enjoyed myself today.
