I got this new Izula a few days ago and it wasn't very sharp when I got it but that was an easy fix with a few strokes on the ultra fine rods of the Sharpmaker.
One thing I really did not like was the jimping on the top of the knife, it was rounded and then coated after that so it was more aesthetical then grippy.
But nothing a small triangular file cannot fix ;)

So my new Izula has got a new set of teeth :cool::D
Now it's the best EDC ever, I love the size, the weight and the design of this knife and it's scary sharp now.
 
I have deja-vu'

I don't want to mis quote him, but i believe RAT said last time this came up, making the jimping sharp like that left the blade more susceptable to fracturing something or other.
 
it was a slight misquote, reference post 16 EDIT: ( :D )

HERE

I dont like sharp edges on my blades because they tend to wear on skin. the only sharp edge i like is the edge itself, and maybe a portion of the spine for stricking a firesteel

Yeah I remember that thread as well
 
Ah that wouldn't be a problem for me, I am not going to use it hard, It's an EDC knife for me so I think it can still open a box :cool:
And I did not make it as deep as he did, I made the teeth a bit sharper but not deeper. But I like his pictures.

That's exactly right. It is NOT smart to do this since it creates stress risers. There is a reason for thos grooves being rounded.
 
makes sense... cut a 90 in plastic it tears easy, round off the corner and it won't tear as easy if at all (with normal stress).

How much stress are we talking about here? Seems like a pretty insignificant change to the blade's integrity.
 
wouldn't it only create the extra stress if the valleys of the grooves were sharpened, I would think sharpening the peaks not so much.

Man, small things can have rather big effect sometimes. Remember those cuts in a blade of a circular saw which increased the strength of it by order of 10 or something...
 
It is indeed the valleys of the grooves that worry me. The sharper they are the easier for a break to start in the knife under stress.
 
wow. thats a serious jimping job. i agree that it may crack. but its to late now. at least you have a good grasp on your knife if something happens
 
Adding stress, Fracturing...... thats like saying the coating is holding the knife together??? don't sound right

not at all actually....they're saying that the sharp corners in the troughs of the jimbing make the material more likely to crack or fracture right at those points....

for example, if you had a thin sheet of metal or something....if you cut into it just like the jimbing done above, it would tear or crack really easily at the points in the cuts....if you made round cuts into it, it would be much more difficult to break/tear and it would not do so at a predictable place....rather it would break where the natural weakness is in the material instead of at the stress prone points you created with the jagged first cut.....make sense? sorta kinda?
