I've had my Tyrade apart in order to put more stiffness in the lockbar, by giving it more bend. Absolutely nothing wrong with the lockup as it comes from the factory, I just like a stiffer lockbar than they come with. In fact I did the same to my ZT0200. But back to the Tyrade. I reassemblied it without the AO just to see how I would like it. I omitted the cover plate when putting it back together because I was concerned it might rattle if I decided to leave it this way. I had no problems with the blade opening inadavertly, but I had put extra bend in the lockbar and that applies more pressure against the blade tang, helping to make it harder to open. I also like a very tight pivot on my knives. So putting both of those factors together, my blade stay put until I decided to open it. Only problem I had was the blade not centering when closed, and I tried every trick I know of to correct it. Being as anal as I am, couldn't stand it, so I reinstalled the AO and it went back to a perfectly centered knife. Your try at this may not result with an uncentered blade, or this may be something you can live with. Btw, I used a heat gun to soften the adhesive under the cf scale on the nonlock side. Once the edge of the cf begin to lift I simply used a small screwdriver to carefully lift the scale on off, revealing the screws. Used super glue to put it back on and it has been no problem since. Good luck if you try this out AM!
