I was watching a special last night on the oldest mummies found to date. part of it talked about cactus spine fishing hooks. it seemed IMHO that they heated them and bent the spines into hook shapes... I had a moment of DUUUH! I made fishing hooks from hawthorn tree thorns I cut, wrapped, an glued with pine pitch and caught a small fish, ruining the hook. made a few more from wild rose thorns either leaving them on the stem and tying off the top or by reatatching the thorns to a carved stick. seems to be a lot of trouble for a one time use kind of thin I thought. Seeing those cactus spine hooks It clicked, why not just heat a bunch of thorn or spines up, bend them around something round and your done... have to trying with some hawthorn thorns but if anyone could spare a few cactus spine of varrying sizes I would love to test this out!
On a side note, anyone else make fishing hooks? made two out of shells and one out of bone and one out of antler.
