mine would probably be my hortons. he puts a edge on a knife like no ones business. they are lasers. the scary sharp to me means you can slice toilet paper with it. it's crazy hard to do. I have seen some of tylers edges that are ridiculous to. he can make them sharp sharp sharp
I have a new composite-blade Kershaw Rake...that's decently sharp. A new composite-blade Kershaw JYD...that's decently sharp. My new ESEE 4 is probably the sharpest, however. 100% factory edge; hasn't yet even cut packing tape.
My Bark River Mini Fox River that I picked up about a month ago came with a wicked sharp edge. So I would say that one for now is the scary sharpest followed closely by my Bradley Alias II.
The scandi grind Blind Horse I got at the gunshow or my Busse Sarsquatch (ask M67) is probably the sharpest from a manufacturer, my sar3 is the sharpest I have put an edge on.
