German market stiletto restoration

This one is interesting. The front and back scales are different. The button is weird too. I’m guessing the original button broke and that’s just a replacement button. That could explain the peaking and why there’s a different scale with no safety. Looks good in stag. Wish he would have fixed the peaking. Definitely a missed opportunity.

That’s right, it had a slip in spring so it wasn’t even an Italian one. Probably Taiwan or China.

Interesting video. But yeah, the blade peek.

You can polish a turd, but all you end up with is a shiny turd. :wink:

I'm still not clear on what exactly causes blade peek - - - on all of my knives that have this problem, there does not appear to be any wear to
the sear holes -- and wear to this area is the only reason I can think of that might cause this condition. Could the retaining pin wear away
enough to cause a blade to peek out as much as a half-inch (which is quite a bit of variance for a tiny bit of wear to a small pin or hole).
What am I missing here?

I've never seen any kind of detailed analysis of blade peek causes (and possible cures) and would love to hear some info on this!

I'll take a stab at it button-man, so to speak.

Causes of blade-peek (I use "peek" rather than "peak" because the tip of the blade is "peeking" out from the liners).

Liner sear-hole worn.

Liner sear-hole deformed.

Blade sear-hole worn.

Sear worn.

Loose sear pin, causing the sear to twist excessively under pressure.

A combination of any of those.

There might be others, but that's the extent of my knowledge.

As far as fixes, it depends on the cause. If it's the liner sear-hole, a piece of metal can be added to basically create a new hole (pinned in place or soldered), or the liner material might be "pushed" using a hammer and punch to produce a smaller hole.

As for the blade sear-hole, I believe steel can be added through laser welding.

If the sear is worn, it needs to be replaced. If the sear pin is lose, it can be tightened.

That's all I've got.

On a related topic, when people talk about storing switchblades open, I don't do it for the spring, I do it to relieve the constant pressure from the sear pressing into the edge of the liner sear-hole. If the liner is made of a soft metal, like brass, over time the hole can become deformed.

It only takes a small amount of wear or deformation to produce blade movement near the pivot end of the knife. And a small amount of blade movement at the pivot will produce a much larger amount of movement at the blade tip. I'm sure there's a scientific explanation for that, but I don't know what it's called.
