I bought the combo edge one when they were discontinued for $39. That was the best Spyderco deal I've even had. Love the stretch. Its a great knife. Mine does not have Sal's mark on the blade.
I've been meaning to send mine in for repair. When closed the lock bar protrudes out and the blade does not fully close. I hope its an easy fix.
