Cold Steel Recon 1 tanto edge angle?

[dzarren]

I've got a Cold Steel Recon 1 tanto point and I've got a few dings in the blade so im looking to re sharpen it. Ive read in a couple places that the edge 25 degrees, but 50 degrees seems a bit steep, and it certainly doesnt seem like its 25 degrees inclusive. And also, it looks almost chisel ground. Well not chisel ground, but ground way more on one side than the other. It looks as if the side thats ground less is a steeper angle. Not sure about this though.

Can anyone help me out? What angle should I sharpen at?

I might be using a sharpmaker cause some guys selling them new in box for 40 bucks in vancouver somewhere. But I might borrow a lansky or something cause i dont have the sharpmaker yet.

If anyone has this knife or knows the edge geometry please let me know.
Thanks for any help.

If you plan to use the knife for the type of rough use it's designed to handle, I'd say 22-25 deg/side is good. My experience of Cold Steel edges is they are typically sharp, but whatever the advertised edge angle is will vary from side to side and even on the same side plus or minus several degrees. If you're in any way skilled at sharpening, or using a guided system, you'll get more even bevels than from the factory. Not that they can't sharpen, but they don't have time to fuss over every knife. You do have time to fuss over your only knife.

If the edge angles are as high as you say, the Sharpmaker isn't going to work. It's not coarse enough to rebevel a knife like that in any reasonable amount of time. A coarse stone and a Sharpmaker are an excellent combination though. See your native Lee Valley for Norton and King oil and water stones. The coarse/fine Norton India will give a wonderful edge for a work knife. With practice, you can even whittle a beard hair with nothing more than this one combination stone.

This is my preference for tantos, of which I have only one. It's used for rough yard work and such. I sharpen the tip at a pretty steep angle, say 25 d/s, then thin the main edge down to say 15 to 20 d/s. The tip is thick enough to do it's job, hard use hole punching or digging in my case, then the main edge will still cut well.

I realize this is an old thread but I was trying to figure out what the factory grind on the recon tanto is. I took one more or less NiB out into the desert and had a hell of a time trying to resharpen it with a DMT folding diamond hone (actually, I may have hit it with paper wheels before taken it out, hmmm...). Because I messed with it in the field, I don't know what the original grind was. When I put it on my wicked edge last night at 25 degrees, I had to removing a hell of a lot of metal. There's absolutely no way I reprofiled the blade that much in the field with 400/800 hone. I'm guessing it started out over 30 degrees. Maybe even 35 degrees! Does anyone know?

IDK what they are new, but mine is 25* per side now. It was a PITA to sharpen. Now i have it razor sharp again. I have the Gatco diamond deluxe system. Keep working at it, it will get there.
