Mattmann, I found TDI through a strong recommendation of Sixto on this forum. I had said I wanted to go to a defensive knife class and that I had purchased a TDI knife (not knowing it was designed by the founder of TDI) for a defensive knife and got some good advice that I should go to the class and learn from the best!
I'm glad I listened. It was well worth it. Especially when we got to practice everything we learned on a deer carcass. The live cutting portion was awesome (from a training standpoint)..lol.
Here is a link to the website: Tactical Defense Institute - CQPC, Knife & Cane -- Close Quarters Personal Control Class
It looks like the next class is Dec 3-4 of this year.
One thing I did (and do) because I understand time restraints and money. I look for classes that I really want to take from reputable trainers. I look at times I might reasonably be able to attend those classes and I start to budget and save for them.
So, for instance, if I wanted to go back to TDI for their Defensive Knife class I would take the cost of the class, hotel, travel and food and then make a budget for how much I would have to save between now and then, see if I could get time off work and baby-sitters, all that and then, if it was reasonable I'd go ahead and call and reserve my spot and start saving!
It took me two years to be in a place I could take that class but it was worth it!
TDI is in Ohio.
There is Hoffners in Texas: Courses
Now, I've never been to Hoffners so I can't speak for the training but it's there.
Suarez International also does knife classes. Some of these places travel as well so you might want to look on their websites and see if they have anything coming to your area. That's all I can think of right now.. maybe someone else has more info for you.
Hope that helps.
