JD though I own a Nemesis Hellion I really can't tell you alot about it because I havn't used it much. It is s30v, small and light, and had some sharp edges I sanded smooth. The neck sheath seems to hold it snugly without a lock. I bought it as a backup blade and because I like the convient draw froma neck sheath while I'm working on stuff. I had not handled the knife before I bought it from TAD Gear. There isn't much to grip but it is adequate and alot better than a scalpel blade or a single edge razor blade. It will not fit in an Altoids tin.
I just haven't used much so I can't comment on the performance, steel, or ease of sharpening. I will be trying it out more starting now just so I know what I have.
BTW I have been using a TOPS Wolf Pup as much as I can lately. The factory edge sucked. It took quite an effort to sharpen it because of the coarseness of the edge grind. It was more of a saw than a knife, but that is behind me now. The WP has been my dinner knife and baling twine cutter for 2 weeks now. The edge slips over the twine and the gets caught up near the scales but other than that it is OK. The WP is my only knife from TOPS. Likely it will be my last.
