I recently bought a Miyabi Santoku from Amazon. But right away find a cheaper one on Ebay which is also marked as new from a reputable seller. But it's a bit too late to cancel the second one. Now I receive two same knives. But I noticed the second one from Ebay is slightly lighter (204g vs 200g). Looking at the edge, the lighter one also has a slightly shallower edge width at the tip. Plus, the handle of the Ebay Miyabi shows more texture of the wood. All in all, are those difference pretty common in knife industry? or it means the Ebay knife can be a second-hand, or re-sharped knife? Sorry if I'm over cautious since this is the most expensive knife I bought.
