Ok, I have heard those words before, "I am not really collecting", and before long they are pleading for money to stay out of debitors prison and pay for knife rehab treatments.....
Everyone with a few knives they don't carry frequently or at all, should keep a record of model, details of knife, cost, location of boxes, etc. Make that list with each knife getting a serial number. Then write it on a small sliver of paper in pencil and with a toothpick push it down in the bottom of one of the blade wells so you can read the number but the blade closes easily over it. Make a slip of paper with info and put on box if you have one with a rubberband. Reference the serial number of the knife. I know, I know you guys only have a few knives. But four or four hundred this little action with pay for itself in memory heartache ten times over.
On your list have a comments section where you can write stuff like, need to find better one.blade heavily sharpened, etc. Actually, draw a liist with boxes on a page using a Sharpie or pencil, ballpoint ink fades. Put it in one of those clear page protectors. You can take it out of that when want to write something on it.
I am hearing in the distance "I am not a real collector, just like to have a few different knives", well Mr. Non-collector these little actions are good for you anyway. This gives you something for insurance, God forbid an event, gives you something in case you don't happen to be around, especially if you got kids. Good ones anyway. And believe me as you near the age of social security your mind is a little less than the ole steel trap it was in your 20's.
Another method I will mention is index card method. Using same info. with one knife per card.
Over in another web site there is a set of knives for sale in one of those zip open cases with elastic holding the knives. It is selling for a good amount. But think how a list of the knives or even each slot with a slip of paper with knife info would boost up the price even more.
Start now before you wake up and say, I wish I would have listened to the voice of experience back when......
