Rich, I am sure there is an end to the variety of these boys' knives, but I haven't found the end of it yet. "School knife" is one I had sought and finally found at a reasonable price. Unfortunately some sellers think that apparent age has a direct bearing on retail value and price them way above what the market is willing to pay. And usually for examples which may be in near-relic condition. This one is a Father's Day gift from my son. He asked if I would use a modern major maker folder and I sent the link to the boys' knife to him instead. So "baby" makes ten examples now. Time for me to sell some unused, unloved knives from my collection to finance acquiring more examples of this genre before there is a price spike. I love buying old low price-point knives for a low pricepoint today.
