What's new

I think... I've made something special

I don't know if any of you remember, a while ago I made myself a large paddle strop using kangaroo leather. It worked OK, but like most prototypes it had some issues I was not 100% happy about. For one thing it was too big. It looked and felt like I was using a cricket bat to strop on. Second, and more importantly, was the kangaroo leathers draw. Or rather lack of draw. The leather looked and felt wonderful to touch, but there was hardly any draw to speak of. The razor just glided smoothly over it without any drag, and this compromised the stropping effect. It was really frustrating. I really wanted to use this strop that I had made myself, but my TM strop, which is latigo, just worked better because it had better draw, so I ended up always using that.

So the experiments began.

A lot of time (and wasted leather) later and I have the Mk2. The leather has been specially treated with a top secret combination of substances which has given the roo leather a fantastic, smooth, yet grippy draw. It now really does the business aligning the edge. I can honestly say that this kangaroo leather, combined with the special treatment, out-strops anything I have tried. And I have been trying a LOT of things in the course of my experimentation.

The strop itself remains a paddle design. The finest kangaroo leather comes from the smaller animals. Of course this means that it is thinner. Roo leather is supper strong for its weight, but even so, thin means it has some stretch, and that could lead to cupping as it breaks in. So it stays a paddle, although I have tuned it to make it more usable. It is carved out of a single piece of maple, 18mm thick. It has had the stropping surface shrunk to a more sensible 65mm (2.5") x 38mm (15"). I found the easiest way of using the Mk1 was by holding the handle in my left hand and resting the blunt end on the sink or a towel rail. To help this, non skid rubber feet have been added to the base of the Mk2. The wood now has a polyurethane finish rather than the bees wax on the Mk1, which looked nice but was less durable.

I am going to try and make another one this weekend, just to make sure that the special treatment that has given the leather its "super stropping" capabilities was not a one-off fluke. If it works... eureka! I've finally cracked the secret to making kangaroo leather strop the way I want it to. :thumbup:

Roo leather is quite thin, but has really tiny pores making it very smooth and an excellent choice for a paddle strop. It is quite pricey here in the US, almost $100/sq. meter, so I have shied away from using it, but if I could I would. The texture and properties of the leather are really wonderful for stropping.

What you have made look great!:001_smile

If you coated it with some neetsfoot oil, or really any other oil effective with leather, you will increase the draw.

My experience has been more oil=more draw. But, don't go to far. Too much draw and you are going to lose the magic of that very smooth final polish surface.

The old shell strops were very effective because shell has very small pores and is very smooth. Have fun!

I have done quite a bit of leather work over the years, if you have any questions, I would be glad to help. Here are some items just about with me:

Is there a reason you couldn't use use the Kangaroo leather as a top layer on a thicker leather or different material for a hanging strop? Just curious.

Not really, but getting two layers of leather to be perfectly bound and to stay that way for a long time is not that easy. Each leather hide will shrink/stretch at it's own rate. Over time this is likely to develop some issues, no matter how well you put them together initially. :001_smile
 
I wonder what synthetic backing would work?

Now, that sounds like a possibility. Perhaps, a very heavy acrylic felt, a webbing, or some flexible thick plastic product might work for using roo for a hanging strop. The key would be to get something that will accept the top layer, allow for any changes in it over time and not shrink or stretch itself.

Thanks Natchez. Yeah, Roo leather is still pretty pricey even here. The other problem is that the best stuff comes from the smaller animals so there is not much room on the hide to get many strops from, and there is a lot of wastage around the edges because of the shape.

But the result is very pleasing when you get it right, and since I've gotten past the point of nicking strops (You should see my Mk1 now. :tongue_sm) it will last me a very long time.

You can make a hanging strop out of kangaroo, another member here sells them and gets good feedback on their results. I think he is using a different type to me though, and I am more comfortable making paddle strops with mine. The leather I am using is extra thin, being from small hides, and I worry about stretching and cupping without support. So it is paddle strops for me, for now.:thumbup1:

I have given thought to hanging strops with some sort of flexible backing, but as you suggest, bonding in a way that would last the test of time is an issue. I'm thinking having it supported, but not bonded to, a flexible but non-stretchy backing would be the best option, at the moment i'm thinking seat belt material might be a goer.

Any-hoo, it is all just a mental exercise at the moment. The paddles work really well and I am happy. I might make myself a smaller travel strop next using the same process.
 
I've heard that the paddle strops are good for new guys because they are flat and it is easier to strop without rolling the edge over. Also I dont really think my wife would like me suspending a strop in the bathroom. A paddle could just store in the draw.

That looks like a really nice one. I want!
 
Stropping on small Kangaroos...
Just so we are all on the same level here,
this guy is now a strop, correct

:blink:

I've seen that Neil Miller currently are selling Kangaroo strop, he also says in the description that it's a very smooth, finishing strop.

BTW, nice work with the paddle!
Even if it killed this guy

Nah, they just don't like people taking their photo's. If you get that close to them you want to either have a bag of food or head gear and good reflexes as they love to box...

Look at the hook on this bad boy:
