Marcinek I appreciate your commits, u seem to have a lot of knowledge abouts blade geometry. What brand of knife would u recommend me. I need a fixed blade that is tough as nails. About 5 to 7 in blade length. I am a hunter/ woodsman so I need it to be very sharp as well for skinning. Blood can be a problem so I need something that won't rust easily. But I need it to be tough mostly. I have the fehrman but I would like to get something else. I have a passion for blades. I would love to make them but grinders are expensive. I'm going to build one this spring. Any recommend knives would be appreciated.
