I am looking more for a locking blade
Tony Bose ( RIP) the best slipjoint builder in the World IMHO he had a saying ,he'd say ," If you need a lock on a folder ,get a fixed blade "
I always liked those Kabar Dozier folders made in Taiwan for 20 bucks ,good knife for the price I use mine for opening the boxes of incoming knives ,since I don't want glue on the blade of others For $20 a pc you can put a few in different places ,work shop ,truck ,etc
