Sorry Cory, wasn't sure if you were serious or giving me a hard time. I wouldn't know what to do without the thing! That cambium saver is great. It's so simple, effective, and quite durable really. Now, in the past I've joked about how it might wear too quickly, but that's just because I was giving the inventor a hard time. It is quite durable, eventually it wears out, but almost always stays on my rope, in my ropebag ready to go.
You can set it simply with a slipknot from the ground, and it hardly ever gets stuck if you pay attention. It's a very cost effective tool that will help save your rope, save you energy, and yes... even save the tree. I've had one ever since I started doing treework, almost couldn't imagine life without it. Have you ever tried it Cory?
