Saw back blades in Texas?
I've been reading through the Texas knife law threads and I don't think I have come across anything about saw back blades.
Is a saw back blade considered a double edged blade in Texas? My job involves me wandering down over grown allies and having a blade with a saw back thats small and easy to carry would be invaluable (I would much rather have that than a combo blade which I have found useless since the saw portion usually isn't long enough). Also my job only allows me to carry legal blades so I don't know if the tool defense works in this case. Specifically I'm looking at this: Ontario 499 Air Force Survival Knife 5" Carbon Steel Sawback Blade, Leather Handle, Leather Sheath - KnifeCenter
Any thoughts or suggestions? Thanks.
