Probbaly hot from similar fools like me, who now have such funds that 100-200 bucks isn't a big deal for an old knife.
Still, if you look at how much there were back in the day, they haven't gone up by that much. I want to say the Tanto was about 125 bucks back in the 80's.
Here's my collection, it's decently big, and just about filled out. I'd like to pick up a Recon Scout, a large Tanto, and a Tai Pan. I saw an Imperial version of the Tai Pan on ebay a few weeks ago - I think it went for 2 grand, which is a far price for those. Only made 500 or less of them.
Terminator - my first Cold Steel, and an awesome push dagger.
Urban Skinner - got this a few months ago, to compete the 80's push dagger set.
Safe Keeper II
Desperado - scary looking curved push dagger.
Magnum Tanto
Magnum Tanto II - this is the 8.75" version from the 80's.
Imperial Tanto - this is the Damascus version, SN 300 ish. Awesome knife.
Special Ops Tanto - Tanto with stainless pommel and guard. This was the first version to have that.
Recon Tanto
Recon Tanto
SRK - my MRE opener from Desert Storm, then another 3 years in the Army. Fantastic and solid knife.
Trailmaster - lusted after these as a kid, finally got one last year. Awesome knife, this one is the first version of it, with the little tab on the bottom. It's a 2nd, but they marked it that way on the back of the guard, so it's not ugly like the 2nd on the grip as they did later. Truly would not know anything was out of spec with it by looks.
Trailmaster, black
LTC Kukri
Gurkha Kukri - later version, black finish with the plastic sheath. I'd like to get one of the bare steel ones at some point, but they are 300-400 bucks, which is about what they sold for in the day.
Master Hunter
Bushman
Tokyo Spike
Rajah II
Vaquero Grande - 6 inches of curved serated blade.
Large Vaquero
Large Vaquero
El Hombre
El Lobo - got the full set of 3, 4, 5, and 6 inch blades with the curve pattern
Gunsite Tanto, Extra Large - was a rehap project from an eBay sale. Dull, chipped front, raven was missing some paint. Put a nice edge on it, repainted the bird, looks nice now.
Voyager Tanto, Medium - need to get a large one at some point.
Twistmaster, Clip Point, Large
Twistmaster, Clip Point, Medium
Twistmaster, Clip Point, Medium
Land and Sea Rescue
Emergency Rescue Knife
Special Forces Shovel - who else remember all the hype about these and how Russian SF soliders could dig, cut, throw, club, and generally take over the free world via this shovel?
Delta Dart
