HAAS knee ascender patent

I had just the opposite impression of the HAAS when it first came out. Even though I have known about and used knee ascenders for a long time, the HAAS was different and in my opinion, better. The biggest difference was in combining the bungee with the semi-rigid tube, both of which assist in its advancing up the rope. Having the bungee protected inside the tube and extended below the ascender and under tension was also new to me. Knee ascenders have been around for a long time but not in this form and I had found most to be too fiddly for anything but a major ascent.

Now this may not mean squat to most of you but my first impression was wow, what a cool idea, backed up by, hey, this thing works great.
The freaking original HAAS works too sweet....it is ok on a runner but is brilliant on my wrench setup....flawless smooth as hell and never misses a beat...folds up nicely and hangs out the way on a small caritool on my harness...I want nothing else
 
The basic ascenders used are generic, it's how the bottom section is built that makes any of the knee ascender devices unique. Don't see any conflict between the HASS and the SAKA patent-wise, haven't heard that there is one.

I thought everyone knew... It was ME who invented the knee ascender.

It was a cold morning in the foothills of the Swiss Alps, 1902. Carl Prussic and I were drinking brandy discussing the nature of infinity.....

....Ah who really cares anyways.
What I was saying in the other thread was basically, I buy x rings, and I use a Haas. If I thought a better product came out somewhere else I would use it. I will spend my money with people who have worked hard to bring something to the industry that wasn't there before. I will not spend my money with the second people who say, "but mine works like this"
 
I know nothing about the patents, or how they are written. Or wether the saka violates. I was merely pointing out that there were two sides to stories, and only one of them posts on the buzz regularly.

Yeah.....the other side gets his lawyer to send threatening letters to equipment suppliers to stop selling his competitors product. No need to be a shill for your buddy, Mac. I'm sure if he had more integrity he would post more.

You just can't make this stuff up. Coincidence? I think not.

Direct correlation between number of posts on treebuzz and level of integrity.

Straw man? You gonna resort to a straw man argument?
C'mon, Mac. You can do better than that!
Your buddy has the same number of hours in his week as every other guy here. So I reckon he could find time to post if he chose to. Comprehendo?

edit. perhaps Mr. Haas's Lawyer has counselled silence??? Crickets.

@moss - Check the sherrilltree and treestuff merger thread. Nick states that there is a patent dispute. The HAAS is patented, and that may bear on whether the SAKA is saleable. TS has stopped carrying the SAKA to avoid litigation.
