Difficulty: Moderately challenging
Things You’ll Need:
Step1
Purchase a guide explaining the knife patterns and numbering systems used by manufacturers and distributors. Companies maintain well-documented production records, and deviations will be your first clue that a knife may not be genuine.
Step2
Study - do your homework before you set off for the knife show or antique shop.
Step3
Inspect each knife closely, looking for signs of mismatched blades and back springs, uneven wear or patina, and handle material that fails to match the model number.
Step4
Use a strong light and a good magnifier when checking a knife. Repairs can be done with such precision that even an expert can be fooled.
Step5
Ask the seller if the knife has been altered, cleaned or repaired. Restoration reduces the value from a collector's point of view.
Step6
Realize that knives are tools, and styles have changed to meet demands as society has evolved. The style of knife should match the era from which it came.
Step7
Know what materials were commonly used when the knife in question was made. Remember, glues are modern inventions, and old knives were assembled with pins.
Step8
Expect old knives to be worn and blades to have been sharpened. Knives were purchased by the original owners to be used, not collected. You will find some old knives in mint condition, but expect to pay a premium price for these rarities.
Step9
Understand that copies can be made to look just like the real thing, but the materials will be modern and the craftsmanship usually will not be as good.
Step10
Ask a knowledgeable collector or reputable dealer to look at a knife if you are not sure it is authentic. They will rely on experience and expertise, and most are glad to help.
