Looking over the razors that are available online is pretty overwhelming... which one would be best for a new user? I see wedge, 3/4 hollow, 1/2 hollow, full hollow... and then there's 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, etc. Some have rounded points, some are squared off. Why so many styles of razors? I just need a *few* choices to pick from for a new guy getting into this. The razor I bought locally is pictured below-- is this one ok to start with or should I have bought something else? Any thoughts & personal experiences would be appreciated!
