A carefully assembled collection of selected knives will continue to grow in value year after year. The demand for older knives is a definite reality. Regardless of your desires for a knife specialty, you will find buyers, sellers, and traders at any knife show and most gun and knife shows. The most sought after knife in any brand or pattern is a mint one. If possible, collect only excellent or better knives.
Used knives can have considerable value.
But, for the soundest investment, it is more desirable to collect only excellent and mint knives. Remember to take excellent care of your collection, as you are the curator during your lifetime for future generations to enjoy. Moisture and fingerprints are the prime villains to avoid. Check your collection periodically and keep your knives in a dry location. Make an asserted effort to wipe your knives at least once a month.
