Recently I've been on Yourcornerstore.com, just because of such low prices.
I rarely buy from the lowest bidder, unless the lowest bidder is a known, reputable vendor with whom I'm familiar.
There are a lot of snakeoil sellers out there.
If anyone knows any other good site that'd be cool,...
Personally, I think you can't go wrong with
New Graham Knives. I've also seen recommended the following, in the past (in no particular order):
eknifeworks.com
onestopknifeshop.com
islandtactical.com
gpknives.com
knifeworks.com
thebladeshop.com
Sooner State Knives
Most of the above I've seen recommended multiple times.
...because being they have low prices, they have a majority of knives OOS.
Their low prices are likely a result of having hardly anything ever in stock.
Places like NGK don't have the rock-bottom-lowest prices, but they have competitive prices, usually stock what they sell, are
prompt with shipping, don't over-charge for their shipping, have people to answer the phones and email, etc. That's all part of customer service, and it doesn't come for free.
My .sig expresses my buying philosophy perfectly.
