DROPSHUTTY with 1 minor MOD ts285 Twosun M390/Titanium Lock Bar Adjust HOW TO DIY Knife Repair guide
Published: 1 month ago
This one's a bit technical. And Im not sure I totally nailed the instructions... so let's go through it!
To start, any knife with a spring-loaded lock bar (all frame locks and liner locks, bolster locks too) could be more dropshutty IF the lock bar wasn't pressing so hard on the blade. So should all lock bars be adjusted to have lighter pressure? NO! Because, 1 Many knives are already dropshutty. 2 Some knives have a light detent, and reducing the lock bar pressure would make the detent even lighter. 3 Some knives have marginally secure lock-up and bending out the lock bar, even a little, will cause lock-rock/loose lock-up.
Obviously one might adjust a lock bar inwards as well, that would be to cure light detent or lock-rock... But that's for another time!
In the video Im only addressing outward adjustments or lightening the lock bar pressure. So, when should you make an outward adjustment to the lock bar? 1. If you want your knife more dropshutty. If you don't know what that means, it's just the "action" or speed and smoothness at which you blade moves. 2. The knife MUST have a strong detent, as this particular adjustment causes the detent to weaken. A detent that is TOO strong, can also be cured with this adjustment BUT this next requisite must also be factored in that use. 3. The lock-up must be strong! I show in the video what that means, but in short, the lock bar CAN'T be super easy to unlock.
Once you've figured all that out, it's basically a matter of taking the knife apart and CAREFULLY bending the lock bar out, till when it returns to position, it's slightly farther out than originally. This reduces pressure on the blade and allows it more free movement... More dropshuttiness!
