Keedex K-22
This can be difficult to conceal and transport. I liked to hang it over my shoulder and wear a long jacket. But it’s nice to have with you when you need it. I make my own now, using the K-22 as a template.
I keep it in a backpack with other entry tools in my trunk. You can also just wrap it around your waist and take it with you. Another covert advantage to this version is it’s disposable. Just roll it up and throw it away!
Para cord won’t break if the tool is used improperly and this version will bend and actually work better if used improperly.
So it’s cheaper to use this version for a training class.
