Kate86, chefwriter is right. Sharpening gear definitely is something that will make a huge impact. And if we are talking about a budget of $1,000, then my imagination drools with suggestions.
First, talk with your hubby. Ask him about how he intends to sharpen his knives, especially whether his school taught him how to use stones. If he wants to, then getting a 500 - 1000 - 3000/5000 collection of waterstones will be the best possible thing you can get for him.
If he doesn't have familiarity with stones, then a tricked-out custom Edge Pro Shapton Glass Stone Set: http://www.chefknivestogo.com/edproshglsts.html
It's from Chefknivestogo and has everything needed in one package (though some assembly may be required), at a price of $339.00.
I don't know if his intended workplace will supply a good cutting board, but even if not, he can always use a good one from The BoardSMITH. A basic end-grain hard maple board will cost $120.75. The site is here: http://theboardsmith.com/product/maple-2-x-12-x-18/
In a commercial kitchen, there is always the risk of theft. Getting an expensive knife as a gift and bringing it into the workplace can be upsetting if the gift develops legs. Instead, a less expensive gift, but still good quality, would be a MAC BK-100 knife, also from CKTG. Only $110 and not quite so attractive to a thief, but still very good quality. http://www.chefknivestogo.com/macchse10chk.html
Most of the rest, he probably has from culinary school, and your total budget for some very good tools is about $570. Maybe add some knives so you can share the kitchen with hubby, and you're all set to go.
