Hi guys,

i have recently, for the second time now, re-gripped a sword using the skin of a small shark (spotted dogfish). While it looks very cool (shiny grey with white spots) and is a very durable and tough alternative to regular leather, I find that after some use, it begins to wear down. That is, the tiny bumps on the skin (denticles) which give it that sandpaper feel begin to rub off thru use. The skin remains tough and overall ok, but loses some of its grippyness and distinctive colouration. Does anyone know of any treatments given shark skin to prevent it from such wear?

cheers, Adam S.

I dunno, a lacquer perhaps?
I know that most rayskin-gripped swords periodically just have their rayskin replaced as it wears . . . .

Yeah, I was thinking some sort of lacquer could be possible. Oil gives some protection against drying and flaking but it also stains it. Maybe, as you say, it is just used and then replaced. It's easy enough to do as long as you have the material.

Cheers, Adam S.

Hello Adam,
As the grip becomes smoother and not as "grippy", is it because the denticles are being lost, or because the denticles are losing their points?
If you're losing denticles, the skin may have experienced some decomposition. You may have to dry the raw skins more quickly to avoid this.

Hi Eljay,

Perhaps that is what is happening - the denticles are losing their points. For the skin remains strong and still grippy underneath , just less rough , like worn sandpaper rather then fresh. The colour also changes, from a shiny grey to a darker, matt grey. Is this process of the denticles points coming off a normal one then? Is this to be expected when using shark skin grip? Is oiling it at all advisable?

Also, how long can the skin stay wet before it is likely to begin decomposing? It is summer now, and so things dry pretty quick, but I did keep the skin damp for perhaps an hour at least while I worked with it.

thanks, Adam S.
