Old sharpening methods...
#71
Thomas,

Looking at the fascinating photo of the boat axe you posted, I notice that our ancestors made an edge with the burr successfully removed. With the advanced work on burr removal on this exchange, I am hopeful that we may someday catch up with our ancestors! Smile

ps, I really do find your posts fascinating. I just watched a program on the mystery of Chaco Canyon. Those ancient people were truly remarkable, understanding things like 18 1/2 year lunar cycles.

Jan, nice job with the hole in the stone! It is difficult to work in stones with machines!

Ken S, yes, what I know we have not find any burr on all the stone tools we have found so our forefathers must had a very special machine to remove the burr Smile

I think we can learn a lot of things from earlyer knife and axe makers and their grinding tecnuiqe - and that edges tools was just tools, often designed for a special purpouse.

If you search on Google pictures after "båtyxor" (boataxes" perhaps "Scandinavian båtyxor" you will se a mot if them I think, they are beutiful designed and there is not two exatly the same. Some of them are extremt long and thin and extreme nice.

Search also on:

"Stenålders yxor" (stone age axes" to se other types of axes
Stenålders knivar (stone age knifes)
Stenålders dolkar (stone age daggers)
