Frustrating customer service / misleading warranty
Frustrating and somewhat surprising customer service interaction. I see from other reviews that my experience isn't unique, but it's slightly different in that the defect in my knife is a loose/rattling handle. When I wrote to report it, I got the story about how the 30 day window (also unrealistic for me as it was a Christmas present) had passed, and therefore they couldn't perform an exchange. What was odd, however, was that they referenced "small chips in the cutting edge" and had determined that they were "normal wear and tear" even though I hadn't mentioned anything about the blade. Which is fine (the blade), incidentally. I even included a video showing the rattling handle. It made me think that this is a common complaint and that they have a negative response at the ready. When I corrected them, I was told that this STILL didn't qualify for the "lifetime warranty" as they couldn't determine definitively whether a loose handle was a manufacturing defect, even though it's unclear what else it could possibly be. So I guess I'm stuck with it. Strange customer service choice I thought. I'll keep the knife as I still like it (hence 2 stars instead of 1), but I wouldn't recommend them. [Edit, post-response: I see, so it's a Lifetime Warranty, as long as the issue is reported within 30 days. That clears it up. ??]
Response from Seido KnivesFeb 5, 2026
Thank you for taking the time to share your experience. We’re genuinely sorry to hear that this interaction left you frustrated—this is never the impression we want to leave. To clarify for future readers, Seido Knives offers a Limited Lifetime Warranty that covers verified manufacturing defects. We also ask customers to report any defects or damage within 30 days of delivery, as outlined in our Damages and Issues policy, so concerns can be properly evaluated while the condition of the item is still clear. In this case, the knife was reported beyond 30 days after receipt and after use. While we understand the concern regarding a loose handle, issues reported well beyond the inspection window—especially after use—can unfortunately fall into the category of wear, handling, or environmental factors, which are not covered under the warranty. This limitation is standard across the industry and allows us to apply the policy fairly and consistently. We also apologize for any confusion caused by references that did not align with your specific concern—this was not intended to dismiss your issue, and we appreciate you pointing it out. We truly value your feedback and are glad to hear you still enjoy the knife’s performance. While we regret that this situation could not be resolved in the way you hoped, we appreciate you giving us the opportunity to review it and share your perspective. — Seido Knives Support Team
