Here's a link to a page on my site with my thoughts on marking blades: unless there's enough information in a mark to being searching, a potential buyer simply has nothing to go on. Most of the time I simply have to tell them that I can't help. I can't count the number of people who've walked through my shop door, with a knife bearing initials, or some type of logo, asking me to help them find the maker, so they could order/buy another knife. IF you're in any way serious about selling knives, I feel the mark needs to be something that folks can use to easily find you. I'm sure you've read other things I've written about it, but it bears repeating.
First, kudos for making your own stamp! I'm not trying to be a 'Debbie Downer', and I don't know how important this is to you, but if you're going to mark blades, I really believe it's in your best interests to mark them in a manner that will allow people to find you.
