Um, because thats where I was when I first started makeing them, also, the andes splits into three cordillera in columbia, the optimum config for the rake is three sharp peaks, with two wide sloping valleys between. Also, its better to have a name that makes quick reference to the particular pick than to have so say, "the one with the three peaks and the round valleys" I have made some with as many as five points, and less room between them, and it only serves to prove that the optimum is three peaks. Too many peaks get in the way, wide valleys allow the pins to seek their own places. The handles are different too, and this actually facilitates the style of picking that works, I don't think the design would work as well with the standard popsicle handles, the grip is wrong for the type of picking that works.
hi that lock you got there has spool pins in and i have one its a pig but can be done so keep at it do a search for spool pins for info on them
