Hello. Hackett here.
One thing we tried to do at the beginning of the season was limit me to only the tools I would normally carry on me (a knife and a lighter) and whatever I could reasonably be expected to find on site (like: pliers in a glovebox tool kit, welding rod in an old plumbing truck). The knife and the lighter were the only constants, and the knife changed pretty much every episode.
We got product placement from CRKT (
http://www.crkt.com/ ) and I used one each episode. For the most part, their knives are excellent, and this is after abusing them in a manner that would make knife aficionados cry/seethe in rage. The M16-14sfg is my everyday carry/utility knife- it is in my pliers pocket right now. Exceptionally good was the Ringed Razel- on one episode I used it as a ghetto cold chisel, hammering it through a steel 55 gallon drum. Touched it up a little with a stone and it was razor sharp. Really tough, nice knife. Most of their knives were great, but a couple were real duds, crap out of the box- their multitool was garbage- poor ergonomics, lots of little design fails (poorly made/designed pliers lock, driver bits had a tendency to fall out for no reason into an overgrown field, wimpy knife blade), and the side-flipping one was surprisingly poor quality- I cut copper wire with it, and dinged the blade. However, all in all I am very pleased with their knives.
They sent a big box at the beginning of the season, including a little folder for everyone on the crew. When I tell my friends that I had FREE KNIFE DAY at work they all get jealous and regret their own, knifeless careers.
