Ok, can't help myself, marketing hat is on. The packaging of these is what will make the big difference. I'd consider finding an elegant cardboard box just a little bit larger than the planes, then lay in a bit of black foam with the shape of the plane cut out. A tag with the story of traditional wooden hand planes printed out on a heavy vellum.
Take a picture of yourself using the plane with shavings, dressed in pretty traditional looking garb, printed in black and white so it looks old. Something like the attached picture, or printed in . You may be able to add some sort of texture to overlay the picture to give it more age.
Pack the top with plain newsprint (wrapping material for movers) so it doesn't move around in shipping, and sell it on ebay or some other site as a traditional hand made wooden hand plane, an heirloom piece to pass down from woodworker dad to woodworking son. A limited run for the connoisseur. Honoring the tradition of classic woodworking with modern metalurgy.
If it were me, I'd try to find a stash of old newspapers so the recipient is surprised by the age of the papers. Nice touch.
I would include some pictures of classic furniture made mainly with hand tools and planes to make the point of tradition. The appeal isn't to men only, many women would love to give their woodworking husbands who have every possible tool, something unusual like this.
If you made a couple of matching hardwood "hammers" for adjusting the blade, with instructions on how to use it, you could put togeter a kit and charge $100 and up for the kit. Google Elegant Packaging Boxes for images and links to something fancy.
As I said, I can't help myself when I see such an obvious income potential where the game is all about marketing the romance of the thing. It's both traditional and practical, ready to use after sharpening. Or ship it sharp, but put in a note to be careful, it's sharp
Don't know about you Herb, but my shop budget would benefit from $700 in income from scraps.
The more I do, the less I accomplish.
