Line Tamer- A lot of arborists have bought and enjoyed having this product. I might NOT have originally brought it into our catalog if not for a long and respectable list of arborists contacting me directly to ask that we include arborist Ed Bingle's product idea. None on that list had anything to gain beyond wanting to make a cool product accessible to tree bro's. I'm certain that like a lot of tools, some will embrace, while others will not. Unfortunately, based on the small size of the tree care market Sherrill has not been able to convince any manufacturer to invest in the tooling required to make an improved version just for arborists.
Rattle Wedge- In review of Bryan's drawings and my text I see no mention that the product "is a must for every job" or situation, nor is it described as a replacement for wedges ...or Master's guns. It's simply being offered as another tool for arborist's who have, on occasion, voiced frustration about the lack of tools specifically for their profession, not to mention the interest in seeing comrades products brought to market. I can't tell if each of you have tried and don't like the performance of the RW, or are slamming it based on armchair opinion or that homemade video on RW's site (shot on what appears to me "the most convenient location of the day" by the inventor). Has nobody here watched a demonstration performed in a location that made no sense of the technique's necessity? Sadly though, based on Jim L's response, perhaps one of the few actual user-reports in this mix is being shoved under the bus. Where's the love on this site?
Jerry's observation is on target, the taper is acute, leading the operator to require a lot of "gun" on mammoth wood (not cartoon wood), therefor "the note."
Around 1985 Tut (dad) and I (25yo then) took on the same spiral log splitter that no_bivy spoke of early in the thread. Reminded me of the same thing when i saw it. BTW-Biv, this was about the year that Nixon melted the ice on China so that my competitors (and the list is long) might eventually apply enough pressure to foul this business.
