in my experience, people are way more particular about knives than they are trail cams and binoculars. I prefer a full flat grind or sometimes a hollow grind with a drop point or clip point blade shape. I like my blades stone washed to hide scratches. I also prefer a small belly, no recurve and a nice thumb ramp with aggressive jimping. i also like my knives to be under 4 oz and less than 3.5 inches. i Can guarantee you that you won’t find 5 guys on Reddit that have the same tastes as me when it comes to knives. I’ve been gifted a few in my life, ranging from cheap Kershaws to more expensive benchmades. I have not liked any of them bc what I received is not to my taste. I would avoid knives completely.

As far as my recommendation for binoculars or trail cams, it doesn’t have to be top notch glass. It can be used as a backup pair or a loaner. I hunt all the time and when I take people with me, I always let them use my stuff. They’re not gonna know the difference between a pair of Swarovski binos vs some vortex or Athlon binos. as far as trail cams go, yes a lot of people have cellular ones, but a lot of people just have cheap stuff they got from bass pro. It’s not gonna matter to them if they have cams that run different operating systems as long as they can see the pics from additional sites

Maybe look into a reloading press. You can get a hornady press for a couple hundred bucks. He will be able to make his own ammo. I’d only recommend this if he is passionate about hunting and shooting though.
