PS : Been carrying and using heavily at work my THREE , count 'em THREE Cobalt Blue G-10 Para 3s for the last few weeks.
I modded all of them . To start I cut off almost all of the opening hole ((this is the fastest way to get down to a 2 millimeter blade thickness )). I left just enough "hole" near the pivot to where I can easily slow roll the blades open ; YES BLUES that''s my usual as well . BUT there is still enough hook shape to be a wave opener if I concentrate on hooking my pocket . Tricky balance (how much material to cut off the blade) but I have found it .
One knife has SPY 27 (shortened blade to Wharncliffe )
Second knife has a Cruwear blade swapped in ; polished factory sharpening angles .
Third knife has a Magnacut blade swapped in , because I wanted to use that stuff hard and experience sharpening it / see what kind of edge it can keep . Last night I reprofiled it to 14 degrees per side polished bevels . Probably a micro bevel there in my future but so far so good .
The MagnaCut dude was push cutting double wall cardboard today with ease . . . side by side I was using my Para 2 S110V reprofiled and convexed for the same task . Para 2 was taking A LOT MORE FORCE to complish the same and was MUCH more comfortable if used in a sawing motion .
Yes this mod on my Para 3s is worth it BIG TIME !
Anyway there's another opening system for ya : not a hole , not a wave , not a tab . . . better ! Does all three .
