I seem to remember that one from a few years ago. Not as good as my mini-tender, though!

That one can't be added mid line...

I had seen it before, but not for sale. Show a pic of yours!

I dont have it. I use one of these:

I used to use a twisted clevis on my lanyard for a tender. It worked well.

Here's mine. Designed several years ago. A collaboration between me and 2 other tree climbers.



I started the process to patent it. Then gave up. It would never be profitable.

If you could fab them cheap, maybe? You certainly wouldn't get rich. But I like it, simple, light and compact.

 

[NickfromWI]

No. How much does patenting cost? Thousands.

You think I could sell 3,000 of these? I doubt I could sell 1,000. That shizil tender is $20. I'd never buy it at that price. I'd just buy a more useful micro pulley.

So my little tender should be like $8. It just didn't make sense to me. I couldn't see a way to actually patent it. But I didn't want to sell it for $20 either.

I wonder about this line on the description for the Shizil on treestuff..

A pulley has several disadvantages, such as causing friction when your line is pulled through against the cheeks of the pulley and causing friction in general.

That's the opposite of what a pulley does.

 

[Husabud]

Yeah pulleys suck. Patents are a joke these days.

 

[tophopper]

I think they mean a pulley may give more friction when pulled from the side due to the rope rubbing on the cheek plates. Whereas their device has less material to cause that friction from being side loaded.

The trick is NOT to pull or tend to the side, and yes a pulley is more efficient. Agreed.

nick, i saw one of your tenders a while back. Robert Phillips had it in monterey and i really wanted one. it is a really nice, elegant piece of kit. its really too bad you werent able to take it further.

 

[treesandsurf]

now if you could take that tender and make a connection point for the rope wrench then you'd have a product!

Nick, yours looks like it has sharp edges, am I seeing it right?

 

[NickfromWI]

You are not. It's quite smooth.

I'm sure it wouldn't be that hard!

He is one of only a few people who have ever been gifted one!

I used this thing religiously until I switched finally to the hitch climber setup.

I was looking at making mine load bearing. It was totally possible to do and I thought it opened up some neat rigging opportunities.

Honestly, if I wanted to make money of it, I would just have a bunch made and sell them in the hopes of not losing money by the time someone started a knockoff, if they ever saw it as a viable product.

I know someone "invented" one a while back and it was made of plastic.

For small time inventions, the patent system is absolute BS.

Mark chisolm has had one on his lanyard for years. I made one out of wood that was not midline attachable, more like the shizl.

I kind of like that little fig8 thing. I just have my lanyard running back through the biner and it works fine for me.
