Starting with a nonstandard Delica. [image] In this case, nonstandard in two ways: it's got HAP40 cored SUS410 clad steel, and a Wharncliffe blade: [image] That faint line you can see running parallel to the edge is where the SUS410 ends and the HAP40 begins. SUS410 is very stainless and HAP40 is very strong -- it's a Hitachi steel with the same formula as CPM Rex 45. It will patina with light use, unlike the SUS410, which is pretty much just there to be stainless and to keep the core layer from cracking from stress. You can try and stop it if you like, the patina, but most people just let it go -- once a patina forms oxidation of the base steel stops. To break any knife down I usually start with the clip. [image] Clip fasteners are nearly always T6. Grab a Torx T6 and undo the clip screws. One of them will probably have some threadlocker on it and will take additional grunt. Not much, tho. Spyderco's generally cool about not daubing on threadlocker like they're...

[image] I'm glad I finally pulled the trigger on (Mass)Drop's Terzuola CTF after 8 months of thinking it over. The knife is well-made, easy to carry, and the blade shape is highly functional. I love Terzuola's mark and the anodized titanium hardware. I ordered the CTF last December for just $87 using Birdshot IV's $50-off coupon code combined with the site's $25-off promo :)
