i made one from tough webbing and elastic sewn together with strong fishing braid, it works a treat but took me a whole evenning of sewing on the sofa! so afterwards i wondered whether it was worth the effort or not?

I made a saka type knee ascender. I like the saka type ascender, but i can't buy one ! I like making things, it was a rainy sunday afternoon, and the parts I needed had arrived in the post.

I bought a stein knee ascender when I got all my srt kit recently. Every time I got to the top of a rope walk, I'd be flustered and uncomfortable. The elastic going over my shoulder to my side D was really digging in.

For me this is a great help. I had thoughts on making something that straps to my leg, but that was before I'd even learned to use my kit. Since using the kit for a little while now, I've realised that actual rope walking is not happening so often during a climb. So it's no hardship to clip this on now and then.

This cost me £60. The ct simple ascender was £42. Not a big budget build at all, and for me, it is well worth it. I already had the XSRE biners and paracord. I had to buy the ascender, amsteel, blue pipe, and heatshrink. I have enough amsteel, and heat shrink left for many other projects. I like how it's all in one unit, with no bits of cords hanging around.

It's light, small as it can be, and flexible.

As you will see from the picture, it's a straight pull on a doubled over 4mm bungee. That's perfect for me and my gear. If I swap the lower XSRE for something a little thicker, like the non ppe biner that came with my stein one, then it can be configured to pull longer. With the bungee going in by the ascender, down the tube, around the biner acting as a redirect/pulley, and back up out to the top XSRE. Not as efficient as a pro job with an actual pulley, but it does work rather well. I prefer it how it is now though.
