You have to consider that consumer protection laws differ a bit from US standards. Over here in Europe its first and foremost the sellers obligation to deliver a flawless product to his customer. If there is a defect in the product, its the sellers obligation to take it back, not the producers obligation. The producer may be responsible to take it back from the seller but thats a different story and not a matter for the customer.
Nevertheless, you should contact Lionsteel directly via Mail. From my experience, they have a great customer service. Some years ago I wanted a set of olive wood handle scales for my Black G10 M5 (just different handles, no replacement). They replied to my request within hours (!) and send me the scales for 20 EUR. They could have told me to just buy the olive wood M5 for 150 EUR but no, they just sold me the extra scales for my G10 M5. Imagine that with Benchmade or ZT, selling parts/scales - unthinkable! I contacted Benchmade twice for dymondwood scales for my G10 Crooked River, didnt even get a reply...
