Overview

The Slice Auto-Retractable Mini Box Cutter pairs Slice's safer ceramic blade with an auto-retracting mechanism, so the blade pulls back the moment it leaves the cut. That makes it a strong choice for safety-conscious workplaces.

At $15.45 it is the most expensive knife in this group, and its 4.3-star average is the lowest here, though still well within our quality floor and backed by a large 7,018 reviews.

Slice does not list blade length, material grade, or weight for this model, so weigh it on the safety design, the price, and the broad review base.

Pros

  • Auto-retracting blade for added safety
  • Ceramic blade resists rust and stays sharp
  • Large review base of 7,018
  • Mini size for controlled, one-handed use

Cons

  • Highest price in the group at $15.45
  • Lowest rating here at 4.3 stars
  • No blade length, grade, or weight listed

Performance notes

Auto-retraction means the blade only stays out while pressed into the cut, which limits accidental contact; the ceramic edge adds rust resistance and long life. Without published dimensions, expect a compact, light tool similar to other Slice minis.

What buyers say

7,018 reviews at 4.3 stars show solid but slightly more mixed feedback than Slice's 50301; buyers value the auto-retract safety, though some may find the price steep.
