Our take on this knife is pretty simple: If you're looking for a sub $50 spring assist knife chances are you won't find anything better than Smith & Wesson's Black Ops SWBLOP assisted series.
Smith & Wesson's latest offering is compact, sturdy and performs like a much more expensive knife. To open the SWBLOP series just give the ambidextrous thumb-stud a push. Just a small push will do it and the knife takes over. The blade opens fast, locks up definitively and is simple (and easy) to close again. The SWBLOP series has a convenient front mounted safety which locks the blade closed at your discretion. The composite body is super dense, but still lightweight. It's textured design provides a comfortable grip. Using the clip the knife rides well in the pocket (the removable clip provides a nice deep carry leaving only about 1/3 of an inch visible). The black coated 4034 stainless blade comes super sharp. The design is both practical and aesthetically pleasant.
By our standards this is an exceptional knife for the money. If offers all the speed and convenience of an automatic knife in a well designed spring assisted package. This is a purchase few would regret.
