titanium bump questions

[A druid]

first and kind of embarrassing is it a convex grind or a saber grind I have it in hand and is either slightly convex or actually saber not sure

second question is a compatible with sharpening on a sharp maker without reprofiled in the edge.

Third the flipping action is a little bit weak is this just a variation or because it has been New in box closed for a fair amount of time.


Last how durable is the coating mine is green is this more common

in response to question one: how much does it really matter? After some use and some time on a sharpmaker every knife becomes flat ground.

I would assume so, the sharpmaker will just slowly reprofile the edge.

probably the latter, the torsion bar is under stress in the closed position, leaving it that way for a long time is bad for it.

I assume it's durable, but that's mostly because it's a kershaw.

Here's my take:

1. I believe it is flat saber ground. I'm pretty sure it's not convex.

2. You can sharpen it on a Sharpmaker, but due to the recurve you should only use the corners, not the flats.

3. The flipping action is not very forceful, but shouldn't be weak. If it's not opening all the way, it's either stiff or you have a bad torsion bar. If it's opening all the way when you press on the flipper, that's all you need.

A steel spring like the torsion bar should not get weaker in anything under several decades if it's designed correctly, which the Kershaw speed safe system almost certainly is. Keeping it in the closed position shouldn't make a difference. They are designed to be stored in the closed position.

I wrote these questions and kind of a hurry what I meant to ask is is the primary grind the flat of the blade hollow grind or flat

as for the assisted opening I'm not sure if I open it to the point of balance where it is about to open and nudge it gently it doesn't quite lock, it feels like the spring as decent tensioned if I press down on the blade closing it. so it might actually loose up. to the point where steps cleanly under the force of attention bar alone. I may loosen the pivot a little bit but if it has Loctite on it I may want to leave it in the factory position.

This is not a knife though be using a lot and with the steels relatively high wear resistance sharpening will be much of an issue, however I would like to know whether Kershaw offers a sharpening service.


I feel like I am being unfair to this knife if a little force is applied just normal flipping action from the back or a little flaky if opening from the thumb stud it opens fine and locks firmly. Also became relatively sharp extremely sharp on the flat and only very sharp in recurve section this can be my imagination but I can imagine that as they are hand finished the recurve must be harder to finish perfectly. The knife if the hand very well in handle is beautiful. I don't know the dimensions but the blade seems to be relatively thin in a good way stout enough yet than enough to slice. The clip is a very well fitted and suited to the knife although I can't help thinking that a custom green anodized titanium clip would be really good looking although an expensive option.

Yes they do. Just send it in with a letter explaining what you want done.
Kershaw offers free tuneups and sharpening on all there knives for life. :thumbup:
