Blenheim operates in a pretty unique space between the artisan stuff we see here and expensive factory made stuff (higher end Shun, Miyabi, etc). From my understanding, they're definitely not the one man shop type smithy we associate with Western makers here but not quite running at the scale and specialization of something like a large Sakai house.
Their target seems to be someone who wants something more interesting and "handmade" than a Williams Sonoma special but also isn't someone looking to pick up a new hobby. I've bought several as wedding gifts for close friends and have never found a meaningful defect on one. I've sharpened them and not had any complaints. Are they something that really tickles my fancy? Not so much, but I think for the price point they sit at and the target audience they're quite solid.
