The use of power tools (Belt Sanders and Bench Grinders) can remove excessive metal shortening the life of the blade as well as annealing the metal and taking away it's original temper. They just cut too fast and too rough IMO. Just saying.......
I find that it is best to stay on top of knives. By that, I mean do not let them get really dull! Once they get
very dull, they need to be re-profiled and you have to basically start from scratch once again. If you do a a few passes on a very hard Arkansas Stone
once in a while, they never really get dull, all that is needed is a few strokes on a very hard stone, and they will last a longer time. It also makes cutting way easier! Heck, I use my Pocket knife to cut a V-notch in my cigar because my pocket knife is sharper than the Cigar cutter is.
Another trick (if you have a multi-blade knife such as an old fashioned pocket knife) is to dedicate the different blades to different tasks. I keep the Small Sheeps foot blade super crazy sharp for cutting my cigars and "surgery work" - ha! The middle Clip blade is kept at a larger angle so its sharp but
very durable and the large main blade is kept somewhere in the middle (sharp & tough) for rope, wood, cardboard and general use that required a large blade. This way you have minimized how you wear the smaller super sharp blades and always have something to get the job done. Sharpening angles are another subject for another discussion though......
One last "trick" - if you are in the "field" and need to get your blade a bit sharper, strop it on the pant leg of your Jeans. It will straighten out the burr on the edge and effectively give you a sharper knife temporarily.

Be careful!
THE DOWNSIDE OF HAVING A SUPER SHARP KNIFE: You will be the first one your friends and hunting buddy's ask to lend them your knife LOL!!
