Byrd Wings Slipit, very good knife. 50ft-Trad and Farmmnan both own them and I know they rate them a lot. Be careful when shopping around though, there is also a locking version out there so make sure you are looking at the Slipit (what Spyderco call their non-locking knives). Another option is the Byrd Tern, another OHO non-locking knife but with just one blade.
