I was looking for a knife for whittling , looked into the case Seahorse Whittler . I bought a knife on eBay for 52.00 was a case xx seahorse Whittler with walnut scales new in box . The knife is numbered and has a knife collectors club on the blade . I bought the knife to use not to collect , am I wrong to use a knife that is numbered . What separates a collector # knife from a user .
