Is it flat on both sides coming to a zero edge? Is it just a flat grind that does not go all the way to the spine but still have a secondary bevel?

Thanks. RL
 
My guess would be the former. Chisels are ground to a zero edge so any significant secondary bevel starts making the knife decidedly un-chisel-like.

And isn't the latter a Scandinavian grind?
 
It sounds like a non-sequiter. WHere did you hear it?

A chisel grind is a parallel piece of steel with one sode sporting a bevel (or bezel in tool speak), and the other flat. You could replicate that on two sides, and call it double sided, but it would then just be a standard grind patern, not a chisel grind, though there are chisels with this grind, but it's rare.

Chisels often do have micro/secondary bevels on them, so the idea of it being two bevels on one side isn't all that odd, however that isn't double sided.
 
I am to make a Tracker after the Beck version. The specs I have received say that one of the grinds (there are three if the hook is counted) is double sided chisel. I swear though the pictures I have seen so far make it look like there is a secondary bevel.

I agree with George, ask the customer. I have an Emerson War Spec that has a chisel grind with a secondary bevel.

I assume your customer is talking about the so called slicing portion of the blade ( I have looked at the trackers, considered building one and decided they were like Bill Clinton...No reason for them to exist)

If I remember correctly they do have a secondary bevel on the chisel portion. I hope you charge more than you feel you should Rodger because that thing is gonna be a bear to grind properly. Then you have to put those saw teeth on the top and try to figure a way to make them ....saw.

Good luck!
 
Yep...secondary bevel!

I may make one just to retain the "Ugly Knife" Crown :footinmou
 
Well, yeah - the customer can have a single bevel if he prefers but I just wanted to know what a double sided chisel grind is, if there is such a thing. The specs say that for the edge closest the ricasso. All the pictures I have seen so far make it look like all edges have a secondary bevel.

As far as ugly goes, every part of it is designed for specific and different functions. I think functionallity removes the ugly. Looks a little big for trout fishing though.

I suppose Rodger....somehow I don't consider scrimshaw a necessary survival skill. Anyway, I did a little looking and darned if it doesn't have a flat grind on both sides. It appears that a double chisel grind is a standard flat grind.

I'm emailing you the PDF manual. That should help clear it up.

Good luck. This one will try your patience.
 
Roger - good ol buddy ol pal - Guess what ?

I have a Beck tracker my friend. If you need me to I can get close up photos of the whole thing for you. See I do add to the forums :D

What I have on my tracker are one flat ground hatchet, one flat ground draw knife that has the hook as flat ground as possible. I know the hook is going to be the hardest part though. There arent any secondary grinds. Just a flat grind with a slight secondary sharpening bevel thats created in the sharpening process. Dont think of it as a secondary grind though. Let me get you some photos shot tonight.

Dont you just love the forums?
 
Roger - call me tonight after 6 if you need to ask about a certain area on the knife. My phone is on my website.
 
BL,

You are too kind. I will call you but not this evening because I have been up on knives since yesterday. I will hit the sack soon and have no idea how long the sun will have fallen before I awake.

I probably mispoke or was too assuming if I said secondary grind. I should have instead said secondary bevel. So then according to you all edges are seconadry beveled, just as the pictures have indicated. Very good and it seems to appear that the term double-sided chisel grind is more of a marketing attempt than of technical accuracy. You have gone a long way in helping me and I thank you. Pictures I have a bunch of and from various angles. The hook is not the problem I think the self cleaning saw teeth may be.

Not to sound like a spoil-sport, but have you talked to Beck about using his design?
 
No I have not and have no intention of doing so unless I have to ask his advise on how to make the self cleaning saw teeth. My customer wants me to make one for him and I will try my best to do so. Aside from all that I am not aware it is his design. Isn't he among several that have made it from the original designer. I will say this: It is his craftsmanship of this knife I admire the most and therefore wish to try to emulate it. and; there ain't nobody that bends further backwards than I to give proper credit to the actual designer. I have no problem making this knife (if I can).

he told me that it was he and a couple other guys that came up with the design. I dont think it his persay but he his most known for it. Tops is doing a version because beck turned down Tom Brown to mass produce this knife and tops jumped on the producton version. There alot of mix up on this subject so I may have some of it wrong myself. I would say just call him if you need to but I dont think he can stop you from making a "reproduction" of his design?

I am all ears on this subject myself :confused:

Spoil- :D :footinmou :) sport
 
I was already told before hand I was going to catch it if I made one of these - and I haven't even put the steel to the grinder yet. I am going to try to make one. After that I don't care anymore. This blade can help teach me things. I marvel at its design, especially after considering its' intendened various functions.
