I've received several interesting what-if questions about this.
Basically, the answers boil down to this:
1) If you are using
a) the likeness of Rob's logo
b) the likeness of Rob
c) of course one of Rob's knife designs
a) and c) are the property of Simonich Knives LLC, and would require their approval to do a tee-shirt or create a knife around them.
I'd be interested in hearing a lawyer's opinion about b), but I'm including it here because I think it belongs there out of courtesy to Christine.
2) If you are thinking about approaching a knife maker and saying, "Hey, what would you think about making 10 of your That-Maker's-Cool-Design-Name knives with special attributes a,b,c (where a,b,c doesn't include the use of Rob's logo) and selling them to raise money for the Simonich family, if you are thinking about approaching Crucible to donate the steel,etc.,
that is simply like a maker putting up a knife of his design for auction to benefit the family. This type of thing is happening already, and will be hugely appreciated.
Why is 1) so important to be careful about?
Legally, because any use of a company's product or their logo in this way reflects on the company and affects its Goodwill value. Goodwill is an intangible - it includes reputation, brand image, etc. It matters a lot when you sell your company. It is in the premium that the buying company pays over the more straightforward calculation of a selling company's tangible worth.
Ethically, because the logos and designs are the property of Simonich Knives LLC, not anyone else's. They aren't up for someone else to tinker with just because Rob is gone. Those decisions all need to be made very very carefully.
I've seen some really nifty tee-shirt designs floated. They all can't get made. If your design isn't carried forward, please don't get all upset and take your marbles and go home. Rob would call you a whiney-butt!
Most of the questions I'm getting are cool ideas related to # 2). Just don't auction off a kidney
