The Slimfoot Auto: a Geoff Blauvelt design and ARCFORM's first automatic knife. Manufactured in partnership with Pro-Tech Knives in the USA.

The concept for this Arcform Slimfoot was to create a USA-made, automatic utility version of the classic Slimfoot. The result is a slightly more compact variation of the original, with a deep carry pocket clip, simple design, and clean lines. The Slimfoot Auto features a 6061-T6 aluminum handle with a black Type III hardcoat anodized finish. The coated 154CM, a tried and proven steel, is easy to field maintain and will hold up to extended use. Best in class automatic action from Pro-Tech provides fast and reliable deployment. A Tritium insert in the firing button gives the Operator model a splash of flair. This knife is built as the perfect EDC knife.

Customer Reviews

ALEX L. on Jul 19, 2023

Bought it as soon as I got the back-in-stock email. Awesome! Sleek. Sturdy. Quality. Badass. No logos. Just a sliver of tritium against a murdered out chassis. Comparable in size to a full-sized Bugout except heavier & thiccc-er. Feels great in hand with a smooth strong swing and “THUD!” -HOLD ON! Lockup is tight w/ nearly no play! Button is a bit gritty, but overall action is butter! Sheepsfoot blade is sharp from factory and has been slicing tape and breaking down boxes like a hot knife… u know. BUY IT!
