These gifts are daily use items that will make their jobs easier.
I've carried a Victorinox knife since I was about 10. I do sometimes carry a simple blade, but a Swiss Army knife is absolutely essential in my EDC for fixing stuff, maintaining things and generally being handy.
Waterproof notebook for patient notes and accident diagrams. This notebook is organized in SAMPLE format, so it's got prompts for all the common patient information. This can be a big help in keeping your paperwork organized and handoffs crisp!
Waterproof ink in a compact pen that will write upside down and in extreme temperatures. It's perfect for a front shirt pocket. Just hang on to it, it's a nice pen!
A stainless steel kanteen. Durable and completely BPA free. This is a tough little bottle that you should expect to keep for years. It's small enough to fit into a messenger bag or backpack and still carries enough water for the day. Please note that this isn't insulated, it's mostly for water.
Everything you need to stay away from fast food! A burly little lunchbox that is BPA free. I've been using a Bento style box lately, but I still like the simplicity of this one.
A durable belt that won't slip. It's smoke jumper approved! I like that the excess belt has velcro that keep it from flopping around. It's professional looking and the buckle has a nice finish.
A nice concentric beam of light, a nice pocket clip, and a pupil gauge. This is pretty much a commodity item, but some of the cheap ones are better than others. These seem to be above average for their price point. I really like that they are cheap enough to toss when you need to!
A simple pulse-ox meter, perfect for your personal equipment bag. This isn't rated for medical diagnosis - but it's perfect for keeping you own bag. If you're used to having one in your rig, it's nice to have one at home in the medicine cabinet, and for this price, it's really reasonable to have one of your own.
