A word of warning, while I used to have some good experiences with Kitchenknives.id shipments, they warned of some customs changes last year. After that, my shipment took 3+ months. Considering the low price and ease of working with them on custom orders (which remains unchanged in my experience and I've seen various grinds including very thin hollow grinds, wide bevels, full flat mid-weights to workhorses from them) I figured it was worth the wait.
A couple months later I ordered a couple customs, then while those were being finished added two more. They asked if I want to ship the initial batch, or wait and ship them all together. I elected to wait and after checking in at the end of December, heard from them on January 1st that they were shipped. Unfortunately, I'm still waiting for them.
It does seem that access to tracking is not available to them, whereas it has been prior to the changes they notified me of last year. They have remained responsive to throughout, but I think it's fair for folks to understand there's a bit of risk involved. Is it worth it for the price? Perhaps, but to each their own. I do think they offer value and a cool opportunity to experiment on designs. I might try again in the future, but probably only for 1-2 knives at a time.
