I have the tweezers in the SAK. I have little sewing kits, but for a day hike I've never had to use it, so i took it out of all day kits. A lot of the areas I'm in you can't use a magnifying glass for fire ignition, the tree canopy it to dense. This was to show what can be carried in a belt rig. I don't usually carry all that stuff for a few hours or a day hike.You mentioned not carrying a mirror because other things can be used for signaling. Just a thought, I carry a mirror, magnifying and a small sewing kit in my "first aid" kit. I've never needed to signal, don't really sew in the field and I don't usually use a magnifying glass for fire but I use all three digging out splinters and thorns.
