Depending on the maker, prototypes can be very close to production pieces. The problem with tooling for a proto is the cost of the tooling. Anywhere from $5K to $30K depending on the model. If there are changes, then new tooling is required. Most makers in the East are smaller shops...

Update, Thanx fer askin'. We recently received protos designed by bushcraft experts that seems very nice. I'm studying the pieces. We also received some very good sheath input from Tiffers & Red. Now I've got to put it all together to plan production. We're also tring to plan a...

Hi Red, I got Tiffers email. I've just been snowed since the blade show. I'm currently carving a handle. I have also purchased, and am still doing so, a number of bushcraft pieces to study. I'm also waiting for some outside designs from experienced bushcrafters. It might be fun to...

Thanx Andy. That was a concern of mine as well. Acutally I'd like more input on the grind angle of scandi grinds as I have no experience with this grind. sal

Hi Red, What's a "slide rule"? :rolleyes: ;) sal

We're open to kits. Let's finish the design and go from there. I'ver changed the pattern of the handle twice since the first blade was cut. I'm still not satisfied with the ergos of the butt in the edge up thumb on bottom of handle position. blade is still the same. We found that...

Hi Red, A poll on handle materials would be great. Is wood preferred by all? Hey Ted, At what level of finishing would you want the blank to be? Cut out. cut out & heat treated. Cut out, heat treated and surface ground to thickness. Cut out, heat treated, surface ground and bevel...

Hi Steve, No plans for a blackened blade on any of the versions. sal

Great thread Martyn, thanx much. I'm open to any and all woods except Cocobolo. My wife,Gail, is highly allergic to Cocobolo. sal

We're doing the math on a 30 degree Scandi on a 3mm thick blade. sal

I think I'm going to change the "butt" a bit, it's a little "hot" (uncomfortable) at one point which needs to be softened. I'll know more when I begin carving the handle. "Jimping" (file lines) on the spine in front of the handle. How long should the jimping be? Spine must be sharp to...

Thanx, it's a start. Actually, I'm just trying to interpret what you are saying, so I can't take credit.....but you can. Hi Tarmix, Yes, we would skeletonize the handle as much as we can without sacrificing strength. My philosophy in design is much like Nature, "No more than...

Cutlery Allied Trade Research Association The machine is made in Sheffield, We have one of about 20 built. The machine tests abrasion resistance on knife blades. sal

Hi Red, no prpblems sharpening anything on a flat stone (except maybe serrations). It's the "sharpening on a rock" part that I see as being difficult with a scandi grind. Camper, I tend to agree with you. We'll get into the "ideal portable sharpner" when we decide on the grind to use...

This is the pattern that we're testing on the CATRA. sal

Great pics Hoodoo, thanx much. Martyn, we ground the first pattern full flat as I needed to do an edge retention run on the CATRA. When we test mules, we grind flat with consistent edge angles so the tests are comparable. We've not tested 52100 yet so this is a good opportunity. On the...

I guess 3mm it is. Sometimes I'm easy, at least that's what my wife, Gail, says. ;) Hi Hoodoo, I'l be hand carving the handle myself to get the ergos comfortable. There has been some discussion on handles being too thin, so I need more input. Best heigth? Best thickness...

After many drawings and "soft" models based on input here and other forums, we do have a "pattern" made of a "bushblade". Nothing is decided yet as I'm still waiting on some outside designs. It's not quite a spear, but dropped a little more than a drop point. The blade length is just under...

Good stuff, Red & Tiffers :You_Rock_ We've penned a simple design fora knife so we can test the 52100 but no finals on the knife yet as we're waiting on some outside designs before we make our final decisions. As Red mentioned, what about the possibility of a fire starter and shapener...

We have a few small protable sharpening designs in R&D. One is a portable with built in angles, one is a diamond/ceramic combination 1" x 5" flat stone, the third is for a convex edge. All are pretty simple. The KISS concept was taught to me many years ago by Dick Newick, a US Trimaran...
