I have to smirk a bit when i see people throw around the word 'best' as a final statement. There is no best people, there are only the most suited for a certain task or your favorite because it's your preference. Same question as 'what's the best steel?' there is none, same reasoning as above.
Frame lock sebenzas/inkosi, compression and axis locks are my favorite when on the couch fondling or to pull out for EDC cutting, but my Tri-Ad lock and back-locks are my favorite when doing hard work around the house, cos i prefer the peace of mind. I like all locks, they just all have different times to shine.
