Here is my .02. I see 2-3 posts a week asking to identify a maker with some sort of mark, animal, flower, hoofprint etc. This might be readily recognizable in the knife making community but outside it can be difficult. I hate to admit I had a guy come up to my table about 10 years ago and asked if I knew who made his knife. We looked all over for the mark. Could not find one for the life of me. All I could see was a gold flower. Then like a sledgehammer it hit me right between the eyes, it was a Don Fog. Now Don is a very well known maker and his cherry blossom is a dead giveaway, But even at a knife show the gentleman had asked about 10 different people and they did not know who made his knife. The other question is I have the initials XXX on the blade but nothing else. Another story IIRC a collector found a knife marked WFM. Who made this knife, no one knew (he was at BLADE). That is until he showed it to Bill Moran, It was an early knife he had made before He began marking with his last name. (I wish I would have found that knife)
I would recommend marking your knives with your Initials and Last name at least. If you are planning on staying in the town you live now then you can mark that as well unless it is too cluttered. This will make it easier for future customers to find you and BUY more knives from you if they like what the see. I tried all the different marking methods and finally purchased a jewelers pantograph and a master of my mark. The mark can be sized to fit the knife and it looks professional.
Good luck in your endeavors.
