If you have been looking for a razor and find the whole process a tad confusing, I'd like to narrow it down a little for you. Do not bid on razors like these:

eBay item 6567330108
eBay item 6566828576
eBay item 6567105312
eBay item 6567105191
eBay item 6567105107
eBay item 6567104866

These razors are junk and they will definitely turn your straight razor experience sour.

And this guy lies through his teeth. His descriptions don't even come close.

In fact, if you live in Chicago, please go kick his butt for me
