It's okay but has some flaws - Wicked Edge Venture Portable Knife Sharpener

I've used a couple other of Wicked Edge's products and loved them so I got in early on the kickstarter for this, and it's a neat concept, but the execution makes the sharpening process a bit frustrating. Would it work in a survival situation to keep a knife usably sharp, probably assuming the plastic slider didn't break. Would I ever take it into a hunting/camping situation for general knife use......nope. Not unless for some reason every ounce counted and I couldn't pack something with just a bit more weight/size that works much better.

The big problem is the slider guide can bind at the end of the sliding groove, why they didn't just put a hard stop here I'm not sure. When it does what happens is on your next stroke the slider binds, this drives the blade off the angle guide and into the "wedge" which causes one of two problems. 1) the system binds up and you have to start over. 2) It moves a bit with the blade at a much lower angle than the guide. So now you've not only had a partial sharpening stroke, but at an angle much lower than it should be.

It's also much smaller than I thought it would be, it's a bit challenging to use with large hands, as there isn't much to hold onto.
