Sal, I know who you are, I love Spyderco products, so please don't take this as an attack, but yes, I do believe that most if not all corporations, knife industry included, engage in unethical practices. Sometimes said unethical practices are legal, often times they are not, and corporations hardly ever care one way or the other (until they get a slap on the wrist.)
There may be a handful of companies that are the exceptions, but why on Earth would one industry be different by virtue of what product it manufactures?
Please consider: what we have seen in these last 2 years, more blatantly than ever before (at least in my lifetime) is that corporations will put their own interests above the public good more often than not, and what real consequences that leads to for the average person (see financial meltdown, oil spill, big pharma outright lying about the efficacy of many of their medications, while trying to hide and actively suppress dangerous side-effects, Supreme Court ruling that corporations have the same right to finance elections that a person does and the inherent inequality of that, a corporate media that keeps the public uninformed about real issues that directly effect them, telecom companies who are trying to lobby hard as possible to end net neutrality, etc, etc, etc) This is nothing new, of course (see the savings & loan scandal from the 80s, the unrelenting outsourcing of the last 30 years, Enron, the complete acceptance and encouragement of that form of modern slavery known as the 'sweat shop', tobacco companies downplaying or denying the harm nicotine causes, and targeting teens with their advertising, Monsanto's war against the poorest 3rd world farmers, the greatest transfer of wealth from lower and middle class to billionaires in history that is our military/industrial complex, etc, etc).
We, as a society, for whatever reason, allow and expect 'big business' to engage in harmful, destructive practices. I hope to see that change.
