I have owned a lot of folders and most of them used some type of washer system for smooth opening action. I bought a Topps Mini Scandi folder and it's the first knife I've owned that has bearings. I've used it for very light use for about a year and now there is a lot of play in the blade even though the screws are as tight as they should be. Now I'm thinking I need to take it apart and replace the bearings to fix it. In the past I have just taken knives apart and cleaned and oiled them fairly easily and the whole bearing thing seems like a huge pain to be honest. Are bearings just a marketing gimmick? To me it seems like more work and less durability for little noticeable benefit. Would love to hear other opinions.
