Eric - That is a very nice fit and finish! Very interesting blade geometry. Keep it up!

The blade looks nice - it looks like a tanto and a khukri had a love child.  I'd love to get my hands on one or see a review from someone who has.

Looks really well made, fairly nice.
But I must admit: the blade style isn't for everyone. Myself included.

Totally understand, it is more of a camp knife than anything else. This knife chops very well and when you choke up on it, it's actually pretty controllable for finer/more precise cuts. It's a big knife, not real heavy, just long, probably not something you would want to carry around all the time, but good to have in a pack or in your vehicle for chores around a camp site. Thanks for the feedback.

Right now, just through me on a custom order basis. There is a gear store in Va Beach called Drajon (pronounced Dragon) tactical, used to be Extreme outfitters, that has one of my fighters on display but until I can get some more made, none in stock. I'm hoping to get at least 3 to him in the next 4 to 6 weeks so he will have some in stock.

cosmology,
True story on the difficulty of getting our particle metal steels from Crucible.
I spoke with a VP of Crucible a couple days ago and he told me that the "making" process is back under way.
Niagra is the only rolling mill that can handle these steels and they are starting back up after re-tooling the rollers to make cleaner and flatter plate steel (guess who you can blame for that  )
What I do not know is the order of material going through the mill and also do not know where our steels are in the line.
Hang in, will advise.

Thanks Bill, the rumors that I'm hearing say sometime after the first of the year they will be selling CPM something, just not sure what grade. In the meantime I've ordered some ATS34 to hold me over. Have you heard anything about Carpenter steel?

Maybe...
...Spent an evening with their management crew and head metallurgist having an adult beverage or two down in Atlanta last summer.
Edited to add: haven't sorted out the Carpenter steels yet.
Will keep all knifemakers here posted on the availability of Crucible steels as I know it.

Cosmok-
The latest issue of the "Knewsletter" from OKCA has an excellent article on blade design for the BladeSports competition. They are big on slightly convex rather than slightly concave (recurve) blades due to the 'grab' of the blade and useable length of the cutting edge in chopping. Have you as a designer/user noticed any large differences chopping with the recurve rather than a flat or convex edge? I have very limited experience with recurves other than the kukri or kukri machete and would appreciate your take on edge differrences before dropping more cash on a 'new' (to me) design.

x SF med, I don't have any experience with any convex type choppers and the only big straight edged choppers are machetes. I can't really give you an honest opinion on this. I can tell you that the gutshot chopper, as pictured, cuts very well. I am able to get 4 cuts on a full water bottle, I guess that would be a soft material and it does well on 2x4's as well. I think the only way I can answer this is to make 3 similar knives, one with each blade style and put them in a little head to head to head contest!! It will have to wait until I have enough steel to make all 3 out of the same type to keep things as honest as I can.

Eric,
Good answer.
I have not made many of the re-curve knives and when I do there is section of blade that is also curved in the other direction.
The re-curve gathers material ahead of the cut and works well in the Nepalese Khukuri because many of these famous blades are also made from thicker stock and are heavy.
If one watches what I think is the ultimate chopping competition, the Stihl Timber Sports Series with the best axemen in the world, it used to be a seven lb. axe was about the weight limit but now some of the guys are using up to 9 lb. axes. It takes some serious horsepower to make a 9 lb. axe move fast.
Mel Lentz was here last week, he is one of the legends of the sport. I watched him chop a couple days ago and noted the axe is accelerating all the way into the strike. Our knives do not have long enough handles to do this well.
There are no restrictions to what axe can be used as long as it meets the safety protocol of being pinned through the head to the handle to prevent an axe head from coming off.
We also have to consider how much a knife can weigh because there is a lot of other gear for soldiers to pack.

Eric,
Not to hijack your thread but you did use the word "chop".
Here is a pretty good story about Lentz with good shot of an axe:
http://sports.espn.go.com/outdoors/t...ory?id=4284667
Big Jim Alexander from Australia was also a friend of mine who spent plenty of time in the shop here too. Jim passed away this year. TR, Jim's hands were fully 1.5 inches wider than mine.

Now, having read that, I will say that Lentz is a tough guy.
Doesn't look that big though.
Alexander must have been a monster.
