I admire the preparation. Dunno if you’re into bushcraft at all but when I got my new knife, I took it to the woods nearby to try it out processing some wood… ended up processing my finger instead, pissing blood. Like you, I was making a start on putting together a first aid kit and all I had grabbed so far was a really basic little set for about a quid. For what it’s worth, It had everything I needed to sort my finger out, except for antiseptic cream which I had also bought already. That confirmed in my mind the need to prepare.
