^^That is a micro bevel from the 30 degree slots. That means the serrations have to be ground a good bit thinner than 15 degrees. With the blade stock only being 2mm and it being a hollow grind, the back side bevel has to be very close to zero degrees so the inclusive edge I bet is around 10 degrees. This knife is wicked thin at the edge.
I won't be cutting up drywall and car tires with this knife, but I think I'm going to give the whole neck knife thing a try and see how it works for general use. I do drive a lot and I've found that pulling a knife out from my pocket is sometimes a pain so it may work for me if I can get used to the feeling of it around my neck. I may need to source a kydex sheath though if anyone can recommend one that has good enough retention to trust. I just can't get used to the tab-lock thingy, I'm too used to pushing the sheath with my thumb to pop the knife out.
It is definitely tiny, and very thin. I don't ever think of knives for self defense, but I can tell you, it is a perfect bartending knife. It destroys fruit for garnish like few others, and can still open all the boxes and cases you want, like magic. No fruit juice inside either, just a quick rinse. I had some pics of home and bar use, but can't find them, so i will include this one instead. I will say, I'm surprised the SE is being discontinued, because I wouldn't consider one in PE, and I really wish the sheath was better.
