It appears that the Canadian maker is no longer active in promoting his product, or active in the MD community.
You will have to hunt for a used one and there are not many of them.
His last post on a forum where he was advertising was in 2016. The website for Ironclad tools says: "Moving to another city. Check back August 1, 2017."
Some event changed his life. Website is up and not updated for more than two years. You could try using the mail on his website, but since he hasn't even updated the moving announcement, it is probably abandoned. Nothing to lose by trying though.
