Got a whopping $39.00 for the hammer plus postage and using Ebay I'm losing a buck on postage. There are also Ebay insertion fees, Ebay final price fee which will be ~$5. Sometimes paypay charges a fee.
So perhaps I will net 39 - 1 -5 = 33
Steel $6 (small order with postage about $1/inch for 4140)
Handle $12 with postage
Tape, cord, screw, pin and wedge say $2
Now 33 - 6 - 12 - 2 = 13
My $13 has to cover
Owning a kiln, bandsaw, belt sander, lathe and drill press
bandsaw blade and drill wear
electricity for the kiln
about 2 hours of my time
I won't be selling any more on ebay.
