Got a Rescue with full serrations back in the mid 90s and used it for years until it grew legs one day. Then I started messing with other one-handed folders for a while, and got side tracked for about a decade. What brought me back is the Stretch. I've probably bought and mostly given away close to 20 other knives, including other Spyderco knives, since I got my first Stretch. Some of those have made it into daily rotation for a while each, but I keep coming back to one of my Stretches. Now there are three of them: VG10, zdp-189, and SB with a forced patina.
Unfortunately, in the last few weeks I managed to hold in my hands and Manix 2 LW, and the XL with DLC coating...I may end up with a couple of those as well. Now if only we could get a Manix action with a Stretch blade.
