Hi guys,


could some makers please let me know what they think of this lockup?

You see, I made this blade a couple of days ago, and posted pics at the Belgian forum.

Now we have a troll there, who tries to tell everyone that the lockup sucks. (the angle of the lockbar is wrong according to him)

Any comments is really appreciated.

Thanks guys,

filip
 
Philip, I am not trying to be a troll. Your work looks good, but don't you think your lock bar should bar should be farther over and fully engage the blade? Your lockup would be maximized then. As it looks now, your lock bar only partially engages the blade. I am just thinking safety here. On this Forum, you will receive fair and honest opinions from us makers, and I think that's what you want/need.
 
It looks good to me as long as she is nice and tight in the open position. Some makers prefer to have more lock engagement than others. But the less lock engagement allows for more wear to occur before she gets sloppy. I tend to shoot for at least 1/2 the thickness of the blade.

I never angle my lock only the blade like you have done. I do around 10° or so, but I am not sure there is a magical number.

I hope that helps.
 
Thanks guys, but before I forget: the blade isn't hardened yet, so the final fitting will be done in a few weeks.

But the guy says that the frame is cut at a wrong angle.

According to him, I cut the blade at an angle, and should have cut the frame at the same angle.

I don't agree with that at all. I would tend to think if the frame was cut at the same angle as the blade that the lock would move/slide out of the way when pressure was applied to the blade in the closing direction.

You don't want a ramp against a ramp. But a ramp against a flat allows the lock to peform like it should and transfer all the force down the longitudinal axis of the lock, there for keeping it locked open.
 
It looks good to me. On a framelock, 10° is just right on the back of the blade. A little less for a liner lock. The lockbar should be cut on a 90°. Tell him he's full of bull. :)
 
When you say "the lockbar should be cut on 90°" does that mean the long cut in the frame/liner should be 90° to where the lock fits into the tang?
 
I think it looks fine, as long as it holds that all that matters.

Chiro: I think Kit means that you don't need to angle the face of the liner where it engages the blade.

Thanks guys !!!

Kit, I quoted you on that 'bull' part. :D
 
Looks good to me. I like 8.5deg on the blade so you are all kinds of good. Keep the lock at 90.
 
I agree with the rest.

That's exactly the fit I want to get before heat treat. After heat treating and polishing, it will engage further, anyway.

Tell the troll where to go. :eek:

Show us the knife when it's finished. Looks great from here.
 
I've experimented with cutting the lock face at the same angle as the blade, but was not happy with the results. Blade at 10 degrees and lock face at 90 degrees works well for me. I also "break" the corner of the lock that contacts the blade slightly with a Scotchbrite belt.

bulloney!!!

as for how far it goes over......a square lockbar engages on the front edge, and whether its 1/32" in or 1/16" in or 3/32" in, the primary thing that holds it is the lockbar thickness, the thickness of the web at the bend, and the amount of bend in the lockbar.


there is NO reason why it wont work perfectly well the way you have it.

If you put the same angle on the lockbar as the back of the knife, you can get a lock that slips, or is extremely sticky!
 
I'm the so-called troll Deviant is talking about.
(only I'm not)

First of all, the 90° thing.
I own only 2 framelocks and had a Mission MPF1-S at hand when I came across the pictures of Deviant's knife.
It's lockbar is cut at the same angle as the blade and provides exellent lockup. (so are most of my linerlocks)
I'm not sure of course but it really looks like this isn't the result of wear but was done like this at the factory.

My mistake, I'm sure.

I started a thread in the general forum asking for opinions.
Most people seem to think it wil be OK when it sets and that it just needs a little wear for the lockbar to make more contact with the blade or at least engage the blade some more.

Mr Carson (love your work) posted in that thread to remark that the blade has not yet been heat-treated and finished.
Deviant himself immediately intervenes in THIS thread when the first 2 posts aren't without some (constructive) critisim, and also stresses that it still needs to be hardened and finished.

This strikes me as odd, since on the Flemish forum where he first posted the photographs of this knife, this is not an issue.
In fact, he describes the lockup as '100%', like it is right now in the picture.
Another maker had to point out that it hasn't been hardened or finished yet and that it will set with use but Deviant dismisses these arguments.
I asked him myself if he's counting on wear or final finish to make the lockup more secure but that wasn't the case according to him.
It only became "the case" after people on bladeforums started to make the comments I made.

My conclusion: This difference of opinion has been a learning experience for Deviant.
(all I got from him was a spelling flame)

Please understand I would not have posted here if I hadn't been called a troll. It's easy to become a troll on forementioned european forum. The only comments allowed on knives posted there are 'waauw' and 'beautiful', any constructive critisism will make you a troll over there.
