I'm not totally against tip down but my other compression lock Spydercos (Shaman and Yojimbo 2) are tip up so I'd like to keep them all uniform. On an aside, I actually used to hate compression locks and wasn't a PM2 fan, until I won my Shaman in GPKnives IG contest. Ended up warming up to the design. I'll never say no to a free Spyderco.
My torx bits though, while not the best brand, were in good shape before trying to loosen the screw. The bit is damaged now so I went ahead and ordered some Wiha bits for future use. Hopefully I have better luck with those and I have my fingers crossed that a brand new bit might still bite into the fastener so I don't have to resort to drilling. I may also try using some EZ Grip but that'll likely do a number on the DLC.
