The products most often labeled are the K-35 cleaver, the KS-1 Kevlar shears and the K-870 stripper.
Can we order a small lot, unbranded?
Yes. Neutral stock is held for the core range: small lots are welcome, you can mix models in one shipment, and restock as you sell. Prices are on request — EXW factory pricing.
