I realized how SWEET a Spydie Slippie is!! The only slip joints I had ever had were SAKs. I am not worried about getting bit by the UKPK too much because the only thing I have ever had slam shut on a SAK while using it was the awl or screw drivers and I was using way too much pressure anyways. Any blade work I'd do with a knife like that would be very light so the lack of a lock was not a concern. HOWEVER as soon as I pulled the UKPK out I realized what was so sweet about it besides the S30V blade, G-10 handles, wire clip, ergos, and the cool little signature on the blade and that was the HOLE! Yeah of course it's a Spydie so Duh, but a slippie with a hole! All my SAKs take two hands and usually a good nail to access the blade and tools. With the hole the UKPK is the instant king of my slip joints for the simple reason I can operate her one hand like the other Spydies. I see this little jewel knocking the Delica out of it's place in when I'm taking a lighter duty EDC than my Millie. Sweet little knife and would love to see a sprint run with some cool exotic handle. I guess that may call for liners though but I'm sure they could come up with something.
