So im new at posting and new at straights. Sorry if im in the wrong place for this. I am doing a lot of reading to learn what i can but i was wondering if anyone could give me a heads up on something. What does the different grinding on these three razor say about the razors? The part where they have had an edge put on them. One is smooth and just moves from tang to blade, one has a one step right into the blade and the other has two sets of grind marks. Big thanks to anyone that can help.
