I've used Sandvik, and it's awesome for things like neck mortises and pegbox sides and stuff. Quote Link to comment Share on other sites More sharing options...
edi malinaric Posted July 18, 2018 Report Share Posted July 18, 2018 Hi All - not wanting to change the topic - but has anyone harvested genuine sharkskin? On one of our local beaches we occasionally have young hammerhead sharks lying around after a storm. Often wondered what part of the skin one would use and how to cure it. cheers edi Quote Link to comment Share on other sites More sharing options...

Shark skin is like if you move your hand from head to tail there is the smooth feeling. If you try moving your hand from tail towards the head you get the roughness that feels like sandpaper, something like a 150 grit, maybe 120 or 180 grit. It's been awhile since I've been around sharks. Alive sharks smell very bad and I can't say 100% for sure, but they may smell better to the human nose when they're dead but regardless it's a bad smell. Wear gloves and start cutting/peeling squares of skin, put into a water bucket and sort out when you get home, I guess. Quote Link to comment Share on other sites More sharing options...
Conor Russell Posted July 18, 2018 Report Share Posted July 18, 2018 I've used dogfish skin. Just the white belly is fine enough. I seldom use it, just finishing with a scraper, but when I do, I sand the surface sideways, so that the scales slice at a skew . It works amazingly well, and leaves a fine finish.

edi malinaric Posted July 19, 2018 Report Share Posted July 19, 2018 Thanks Connor - belly it is - any special preparation? I've done the occasional bit of Cape Cobra snakeskin tanning (local garden hazard). Maybe I'll just skin off a strip of sharkskin and try various things. I've searched our local mountainsides for equisetum but nothing doing. cheers edi Quote Link to comment Share on other sites More sharing options...

Michael_Molnar Posted July 21, 2018 Report Share Posted July 21, 2018 A few days ago in Iceland, I had the opportunity to handle some sharkskin. I found it to be coarse and somewhat inflexible. I think your time is better spent making instruments not substitutes for modern abrasives. Quote Link to comment Share on other sites More sharing options...

Hi Michael - yes - but following our recent ban on any garden watering I also now have no almond trees, plum trees, cedar tree. However I have lots of firewood. However winter might not be over just yet - and there's always next year. It works superbly - made by a friend of mine. http://www.earthfire.co.za/ cheers edi Quote Link to comment Share on other sites More sharing options...
