Bought a Kershaw Ken Onion16710BLKST about 6-7 years ago. Pops open like the day I bought it. Lost it out shooting one day. Drove the hour+ back out to find it, and did the next day.
Bought it at a shop at Northgate mall then saw it somewhere else $25 less but after all this time I don't mind. The inlay in the handle is a no-slip tape stuff. Can't tell it's 6-7 years old. Never leave home with out it.
