I've taken to wearing my HEST on a tek-lok, vertical at 8:00. Strolling around the suburbs, even on our "nature trails" it won't get much use, but what you don't carry, you never use, so ...
The Izula is a must-have. It drops invisibly into a pocket -- pants, jacket, vest, anything. Too light to notice. And it's more than half the capability of a HEST, which means a great EDC knife for those who don't absolutely positively have to carry a folder.
Get the Izula to back up a SAK and you're good to go, even in fairly demanding situations. You know the saying: a survival knife is the knife you have on you in a survival situation. The Izula is so convenient, there is no reason (except perhaps legal

) not to carry it.
As far as the Izula being small, I have big hands, and it works fine. For a really secure grip, I tuck the butt into the heel of my hand, my ring finger wraps around with the tip in the ring of the handle, index finger at the choil, and thumb tip on the friction grooves. Absolutely comfortable and stable.
That works for a lunging stab, or whittling, or with my thumb pushed forward, for food prep.
After you've gotten into the Izula, start saving for the HEST, which might replace it, or for the RC-4 or RC-6, which would be the next step up, especially if you plan on serious outdoor time.
