Question to Cliff Stamp

[Chris "Anagarika"]

Cliff,
One question on the CRKT Point Guard. You can either reply here or continue in this thread.

Question is:

The tang of the blade: there is a concave notch (about 3mm diameter) between the surface that meets the lock and meets the stop pin.

What is the functionality of that notch? Why don't they just use a straight line? I don't get it.

 

[Cliff Stamp]

I will be getting another Point Guard shortly to check the behavior of the LAWK's, I'll check out the notch then.

Without a pic it's a little hard to tell what you're talking about, the tang of the blade is slightly concave where it meets the stop pin?

Either it's unitentional, like from wear, user, or testing. Or it's intentional, likely to increase the surface area betwwen the blade and the stop in to decrease wear.

Sorry .. I don't have a cam, can't show a pic. However, imagine this shape -u- of the tang, where the blade point downward.

The first dash "-" is where the tang meet the stop pin. The second dash "-" is where the tang meets the lock. Between the two, there's this hollowed part "u" that I was asking about. It is as if they intentionally grind off that portion instead of leaving it quite straight "---".

I hope that is quite clear... And THANKS!

Cliff, any chance getting your CRKT again?

Here is a shot of the replacement I recieved :

there is a section of the tang which is roughly ground, this is done to increase friction and give a more secure lockup. It isn't hollo though, it is straight on this one. Was this what you were talking about.

Cliff, yes, that's it.

From the roughed up part (in your pic it's a bit brownish in color) and you move to the other part where the tang meets the stop pin (you can see there's a thin line), in between, there's a portion that caves in, you can see the light reflection as a long bright line. This is the part I am asking.

Why the caving in there and for what purpose ... why not just a straight line / ramp ..?

 

[Cliff Stamp]

Ok, there is a hollowed out section right inbetween where the liner and stop pin contact the tang. As far as I can see it serves no purpose because it doesn't contact anything, it might just be there due to how the other two aspects are machined.

Ah .. that's that ..

I thought it is meant to distribute the impact / force or anything .. but then physics is not my major .. merely some interest to understand nature.

Thanks Cliff!
