I have 4 Spyders that I carry often that would be considered "Holy Grail" Spyders.
The C-44 big Dyad
The blue handled, plain edge Spyderhawk
The C-46 Bob Lum Tanto Folder, G-10, ATS-55, CE
Massad Ayoob, SE
But I've had all these blades as users for at least 4 to 5 years plus. When I first became a citizen of Spyderville all those models were very much available at the time. I've had some tell me that my G-10 handled, SE, ATS-55 Harpy is a sacred cow of sorts. I hope I'm not faced with the task of replacing it anytime soon.
Hey I'm into collectibles as much as the next guy but if there's a Spyderco knife that really lights up your life then go ahead and use it for crying out loud. They were made to be used and don't forget that. I'm always open to obtaining back up units to the ones I'm currently using so you might want to consider that game plan.
Long Live the SPYDEREDGE Spyderco Hawkbills RULE!!
