What are the special requirements for a blind car knife?
The tip of the knife blade is greater than 90 degrees (about one hundred and twenty degrees), so that the tip of the blade is protected
Simply put. The Angle of the blade is less than 90 degrees, about 80 degrees. (actually the look line, as long as live not collision hole bottom line, as to how many degrees would amount) this point is more stress, don't car too thick.
Don't put a knife in the top of your knife when you're in the hole. I don't know what you want the car. It's a little bit more than forty five, and I'll use the Yt15 knife. Cast iron for the Yg8's knife. Unembroidered steel with Yw1. A knife with YS8
