Which trail master is better? The San Mai III or the carbon V? Also where are these made, Japan?
The SanmaiIII is a lot more expensive. I had one that was my big user for about 8 years or so.
The edge retention was great. It is a thick beast. The only down side, really, was that the krayton handle did become a bit irritating on the hand after extended use. A quick wrap with sport tape would likely solve that.
The edge on the Sanmai III blade is a full convex to zero edge. Which makes a great chopper. They are super easy to sharpen, once you learn to sharpen a convex edge. No real special equipment necessary. A loaded strop for touching up the edge, and then sandpaper over a mousepad for fixing edge damage.
You might want to take a look at Falkniven Thor bowie as well. Similar price range, but you can get the handle in stacked leather.
If stacked leather handle was an option on the Cold Steel, it would be even better.
The carbon steel version will be much much cheaper. You will still get a lot of great use out of it.
If you are looking in that price range, and going carbon steel, try to find a ScrapYard Dogfather. They are a bit more, but have a much better warranty, and have a better handle material, and design. They don't suffer from the same weakness in the tang shoulder transition. The cold steel bowies have a square transition which can lead to heat risers and create a weak spot.
The SCrapYard does not have this. The handle material is resiprine C which is much much much tougher. Only rubber type material handle that I know of that has a lifetime handle warranty as well.
If I was buying a carbon steel right now, it would also be hard to beat Rat Cutlery (now ESEE knives on here, due to name change). They use well heat treated 1095, and have a lifetime no hassle replacement warranty. The best in the business.
That all said, however, if you are looking for a chopper in the same price range as the Cold Steel San Mai III, Take a long hard look at Bussecombat.com They have a 10 inch Chopper right now for about the same price as the Cold Steel, with a much tougher steel, and a lifetime no hassle warranty.
I sold my San Mai III Trailmaster after getting one of their choppers.
Good luck.
As to the chipping issues with the Laminated steel San Mai III blade, I never had any issues, and I have not heard any. I have seen some broken carbon steel Recon Scouts, which have the same blade tang transition.
