I decided to escape previous thread to clear up some space. Here I made another video explaining, summarizing and demonstrating the problem as well as presenting a possible solution I discovered to fix issues with the current design of vise. At least this solution could work as a temporary bandaid for people who own similar vise designs.
As I understand WickeEdge is working on better design of vise. I’ve researched *ALL* available precision manual sharpening solutions and found some interesting and solid approaches. I’d be happy to share these findings privately with WickedEdge people if they are interested in ideas for better designs.
I do not have those problems with my WE130. You need to send your vise in for a replacement so they can see what is wrong with it. My LAA locks up good and tight even with the tension adjust all the way on the minus side.
I think that the root cause of your issue is that the current jaws no longer have the square flats on them (see pic). I have the Field version from ~5 years ago. I setup my kitchen knife to check for wiggle and there is none either with my chamois insert or without it. I use the chamois to protect the knife surface from nasty little marks due to clamping. I also designed a simple fixture to handle flexible knives and low angles – cost = $5. No wiggle there either.
