Nice Kit Hacksaw!
My repair stuff is scattered in many locations and your idea of assembling it in a kit is a good one, another job for me during the slow times this winter (I should start a list).
Possibly additions depending on space and weight restrictions.
-I have used 5 minute 2-part epoxy and J-B weld in the field before, it may be a worthwhile inclusion in a kit of this type (I once J-B Welded a sparkplug into a lawnmower motor, if you flooded it while starting you had to go have a beer because you could not remove the plug to dry it out, it held for over a year).
-How about a thin diameter drill bit and improvised holder to make holes in things.
-Being a bit of a knife guy; a small blade, SAK or multitool would be a good addition but you proabally have one on your belt already.
-Maybe a piece of hacksaw blade to cut metal, perhaps a small file?
-A few assorted size nails and screws would be handy.
-I have sewed heavy pack straps before and needed an awl and thimble to do the job.
What kind of thread are you including in the kit?
Good post, you really got me thinking.
Thanks,
Mike
