Contact me through the website www.bladefixing.co.uk. if you want to have a try. It will be fully tested when it comes to market, and I'm confident that it will out perform rivals, as far as grip it goes they claim 180kg yet only say safe weight 50kg shear load, and then say 30kg on pull out load, so that is an example of rival claims, I'm offering an alternative that does more, of course it needs tweaking but the principal works.
