Botach Tactical offers discounts on a selection of KZ Defense Pens and Tools, with prices from $8.95 to $11.95. With free shipping on all orders, that ties last week's mention as the best prices we've ever seen on these items.
A best bet is the KZ NAIL Tactical Rescue Tool in four colors for $9.95 with free shipping. That's $3 off and the lowest total price we could find. It features a lanyard hole, stainless steel clip, window breaker, sharp bullet point, and more.
