I would not shop for knives on line. I might purchase them on line after I had done my shopping and trying out in person, but even then, it is possible that what you buy will not be what you saw in the store. These days there are a lot of similar names and lines, and it is easy for unscrupulous companies to sell inferior products by manipulating the names just a bit.
Good knives are expensive, and there is really no getting around that.
If you live oin an area where there are no stores, then I guess you are "stuck," so to speak (no pun intended)
but that's my recommendation.
