In the 70's the Knife market was stagnant. Every company had their "Buck 110" style. Puma had the Game Warden, Schrade had the LB7, Ka-Bar had the 1189. Everyone had the Schrade 227/250 style. Every one had the stockman. There wasn't any inovation. Serrated edges were only on kitchen knives. The only real change was handle material and color.
The attempt at one handed opening studs, clamp on aids for one handed opening and such was pathetic. In the late 70's, everyone was just getting introduced to the crock sticks so the ceramic sharpening market had begun. Oil/wet stones sales were beginning to slide.
Along came Spyderco about 1980. It was solid stainless, functional clip and a working one handed opening knife. The edge was sharp and the only down side was that if you got the serrated edge, you had to get a triangle sharp, since that was the primary way to sharpen the knife. The fast spread of the knife was due to a lot of word of mouth. The people that loved them told everyone about them. by the time they came out with the FRN handles and lowered the cost, they only doubled their market. The solid stainless was a little pricy back then. Now, getting $150 for a para military is nothing. Back then, getting $66 - $100 for the stainless handle series was steady but the FRN handles dropped the entry level price to Spyderco's to about $40 for the Delica and the ladybug was under $20.
When a calf roper walks in and buys a pink delica on sale, since girls weren't really into knives back then and the pink knife was the only Spyderco on sale, that means the value of the knife/tool far exceeds the crap he will get from his friends.
Now practically every knife manufacturer out there offers a serrated edge pocket knife. Most have either copied or inovated on one handed opening blades.
I used to work in a knife store. Baby Goddard is one of my EDC's and still have my Vintage Spyderco sharpener in the heavy zip lock bag.
Lastly, I now live in the Denver area now, so I can drive to the Factory Store if needed.
