I have to agree with Esav, an ESEE 3. No serrations (he will have an issue pair of scissors that is "self sharpening") and a benchmade seatbelt cutter for tearing off trousers in a hurry.
- Weight will be a big issue(medic pacs are heavy), the #3 is lighter more compact and can do anything the #4 can do other than its pry strength.
-Warranty is no. 1 and is backed by Good People.
-His cutting chores will be minimal and God forbid he will not need to stab people. Opening MRE's might be the big chore
-Fixed blade is best when attached to your molle kit for access and habitual locus(constant placement in the same position of anything in order to find it there under stress) hope you understand my explanation.
-Failing this a good folder with a hole opener for gloved, tactile, wet, for sure opening with one hand, would be paramount and a sheepsfoot blade shape, so as to keep the blade away from skin contact when working to take clothing off the body. i.e. Spyderco Rescue Rescue- 93mm or 79mm blade length
CONCLUSION
-ESEE #3 no serrations to fix on kit+ Benchmade excellent with kit.
OR
-Spyderco Rescue 93mm or 79mm for pocket carry (great to have on when doing Medic tent rotations with no molle kit on)
OR
-Both
No matter what you get, I hope that some of the information on the forum has helped you make a decision.
N/B a sharpening device would help- Triangle Sharpmaker from Spyderco, compact, light, easy instruction, guaranteed results.
Congratulations on your son serving with medics- You must be one proud Dad. A thoughtfull gift to boot. Go Dad.
Cheers, all the best with your decision.
