I got mine in Norway.Yes, your jute looks much thinner and tighter weave than any I have found. Where are you sourcing it from?
I also picked up a Tony miller Number 2 strop with flax linen (3"). I enjoy this linen the most so far and use it to strop before the shave. (Got the veg tanned horween strop for leather component).
All of that said, I really like a vegetable tanned horse hide (horse butt) that is left in its original state. Tony Miller uses a horse hide that has a roughened surface, and while I like a stop in that finish, I do have a soft- spot for a hard leather horse butt strop. The leather is very fast with almost no draw, kinda' like a piece of waxed paper and the surface is very hard yielding a fantastic edge IMO and IME.
The horse butt that comes from Horween can vary quite a bit from shipment to shipment and no matter how much one asks there seems to be little control over the surface. Much comes with a velvety finish and a bit of softness, other times some will be a slick, almost polished surface and much firmer. I update my storefront to give choices if I have choices in finish.
They do also offer a hard rolled horse butt with a really firm, slick surface but it comes nearly as still as masonite and mostly unusable for my strops. Short of doing most of the hide processing in house as Mr. Kanayama does, ordering leather is pretty hit and miss. I used to source everything in person but Horween is halfway across the country so at least on horse butt I get what they send and decide what can be used and what gets tossed or given away.
I do wish they were more receptive and could deliver to spec.
Yep, that Masonite stuff is what I like Though it does need some work to flatten it enough to be useful as a strop. The stuff tends to curl edges- up, exactly the way we do not want a strop to be shaped. But if a person is willing to put the time in, I find them great strops, very effective, and faster than a newspaper strop which is really saying something.
The horse butt I got from you with the short nap is also an excellent, having a light draw but more than the slick horse butt. I think it also has much, much better feedback, probably the best feedback of any strop I have used. The bare, shiny horse butt strops have almost no feedback and it is really quite easy to damage a razor's edge on that extremely hard and unforgiving material.
Now that I have said all of that, I will finish by also saying I have liked almost every strop type and finish I have tried with the exception of Latigo or anything that was oiled; I guess I am just not a fan of heavy draw strops.
Leather, and cloth vary quite a bit so it gets harder to categorize any "type" or name as each manufacturer/mill/tannery has their own unique spin on a material, also each batch or run will vary depending on how tightly the manufacturer controls their recipe and even the names we as users call things causes confusion and difference in materials. Linen/cotton/canvas/etc...all describe a cloth component but if used loosely really do not define or identify what that material actually is. Linen has become the generic name for the cloth component now days no matter what fiber is used. Lots of "Cotton Linen" components mentioned out there where cotton is the fiber and "linen" is simply describing that it is a cloth component.
This makes it difficult when asked what leather should I try or what cloth should try as the replies will often refer to either a generic name or one single manufacturer/tanneries product which can be vastly different from another. A good example would be "shell cordovan", the superior Kanayama shell is different from much of the vintage shell and quite a bit different than the Horween shell with the first two created mainly with good stropping characteristics, the later more towards quality shoes and accessory items (now days anyway).
