We strongly recommend a couple of pairs for every serious edged weapon collector. Blades should be handled only while wearing white gloves. Oils from fingertips cause more blade spotting than anything else. One should take a cue from the Smithsonian and other major museums. All curators, assistant curators, etc. are required to wear white gloves when handling museum edged weapon artifacts. These gloves are inexpensive and will more than pay for themselves if one blade spot is precluded.
