Longden,
Look in the Spyderco part of bladeforums for threads on the Starmate.
If you would like my opinion on them (I just got mine yesterday) I will share with you, in concise terms my opinion of it so far.
The knife is awesome. When it arrived it surpassed my expectations. Really solid, the blade is made with beautiful, really thick 440V steel. The knife is incredibly light, especially given the amount of steel in that blade.
The lockup is really solid, and the action very smooth, no play in it what so ever. I've tried different grips on it to see if I could 'accidentally' release it, with no success. I totally trust it.
I have heard other forumites express concerns over the ergonomics of the handle. Personal preferences I assume, as when I hold it, I find it quite comfortable. And I find that the grip is still secure even when the handle is wet.
The lines of the knife are really nice, the blade shape will prove to be more useful to me as a daily carry knife then the knife which it is replacing, being less pointy at the tip. I've carried the Endura every day for 10 years.
I've always loved the Endura (and still do), but after holding the Starmate, whenever I pick up the Endura, it feels cheap and flimsy (which it is not).
From now on I carry the Starmate.
It is a high quality knife that uses all the newest materials, and puts them together in a package that is solid, comfortable, safe, and aesthetically pleasing.
If you can find one, buy it and you will not be disappointed.
IMHO
