I just bought my second straight razor. I have been doing a lot of research on what to look for and the right questions to ask before buying used straights. Hopefully this was a good purchase. The TREE logo dates in the 1924-1935 era. It is an H Boker & Co. King Cutter. It seems to be in pretty good condition, it will need to be polished and honed before i can use it. Since my fisrt straight razor was bought and honed at SRD ill probably send this one to them for honing as well.
