Hi I am getting my first strop and was considering a Fromm ( http://www.amazon.ca/gp/product/B001...A3DWYIK6Y9EEQB ) that is the one in question but I came across the other one from SZCO Supplies, not too sure about them but this strop has a canvas side in addition to the leather. http://www.amazon.ca/SZCO-Supplies-1...A3DWYIK6Y9EEQB

So my question is if anyone knows about SZCO and if I should trust it or go with the Fromm which doesn't have a canvas side. Also is the canvas side necessary?

Hope you can help!

Thanks
