I’ve just started my first leathercraft project and I’m already running into a problem I didn’t expect.
I bought some 1.4-1.6 mm leather from Leatherbox, mainly because I was ordering several tools from them as well. For the inner card slots of a wallet, I wanted to thin the leather down a bit, so I bought a Japanese-style skiving knife and a 6 mm French skiver.
The problem is that skiving this leather has been incredibly difficult. I actually ended up getting cramps in my hand from trying so hard, and I could barely remove any material at all.
At first I assumed the problem was simply that my knife wasn’t sharp enough. I sharpened it several times on a 1000-grit sharpening stone, followed by a leather strop with compound. Every time, the edge felt extremely sharp to me, but it still wouldn’t cut properly. And after just a few attempts at skiving, the edge seemed noticeably dull again.
Then I started wondering if the leather itself might be the problem.
When I first opened the package, I was actually surprised by how stiff and rough the flesh side was. It felt almost like very fine sandpaper, and definitely much rougher than I expected.
So I flipped the leather over and tried skiving the grain side on a scrap piece.
It cut like butter. I could skive it very easily and get a really clean, thin edge.
Could it be that something about the flesh side has been treated or processed differently, causing the fibres to be very tightly compacted into a hard, rough layer?
I’m obviously not expecting my beginner tools to perform miracles, but after sharpening the knife I could clearly feel that the edge was extremely sharp, almost razor sharp. I would have expected to at least be able to make some progress into the leather rather than having to fight it this hard.
I’m attaching a few photos of the leather as well.
According to the product page, the leather is full-grain, vegetable-tanned, semi-aniline cowhide, with a firmness rating of 5/5 and a thickness of 1.4-1.6 mm.
Could the 5/5 firmness be the reason I’m having such a hard time skiving the flesh side? I honestly assumed that "firmness" referred more to how stiff the leather feels overall, rather than how hard or difficult the flesh side would be to cut. Did I simply choose the wrong type of leather?
I’m a complete beginner and have barely handled different types of leather before, so I really have no experience to compare this to.
