Mantis Isosceles 6 3/4″ Folding Knife Review

Let’s Dive into Mantis Isosceles 6 3/4″ Folding Knife

The Mantis Isosceles 6 3/4″ Folding Knife is a compact, frame-lock folder designed by Mantis Knives for everyday carry and utility tasks. Boasting an AUS8 stainless steel blade and a minimalist design, it aims to offer a balance between portability, functionality, and affordability. Is it a worthy addition to your EDC, or does it fall short of expectations?

I’ve been searching for a lightweight, reliable folding knife that I can easily carry without feeling weighed down. Something with a sturdy lock and a blade capable of handling basic cutting chores, from opening packages to prepping kindling. Many knives are either too bulky or feel flimsy.

My first impression was that the knife was surprisingly lightweight, yet felt solid in hand, thanks to the frame lock design. The black-coated AUS8 blade looked promising, and the overall aesthetic was clean and functional. I initially considered a Kershaw Leek, but the Mantis Isosceles’s frame lock and slightly thicker blade swayed my decision. Another contender was the CRKT Pilar, but its stubbier blade seemed less versatile for my needs.

I was initially excited about its potential as a no-nonsense EDC knife. Hopefully, it could handle everyday tasks without feeling like overkill. I also hoped that the frame lock would provide a secure and reliable locking mechanism.

Real-World Testing: Putting Mantis Isosceles 6 3/4″ Folding Knife to the Test

First Use Experience

I first tested the Mantis Isosceles 6 3/4″ Folding Knife during a weekend camping trip in the nearby mountains. The weather was a mix of sunshine and light rain, providing varied conditions to assess its performance. I used it for various tasks, including opening food packages, cutting rope for setting up the tent, and preparing kindling for the campfire.

The blade performed admirably in dry conditions, making clean cuts through cardboard and rope. In wet conditions, the grip became a bit slippery, requiring a firmer hold to maintain control. I found the knife easy to deploy with one hand after a few practice runs.

However, the frame lock was initially a bit stiff to disengage. I also noticed some slight blade play when fully extended.

Extended Use & Reliability

After several weeks of daily carry and use, the Mantis Isosceles 6 3/4″ Folding Knife has proven to be a reliable, though not perfect, tool. The black coating on the blade shows some minor scratches from regular use, but the AUS8 steel has held its edge reasonably well. I had to strop it a couple of times to maintain sharpness.

There are no signs of structural damage or loosening of screws. Cleaning is relatively straightforward, requiring only a quick wipe down with a damp cloth and occasional lubrication of the pivot point. It outperforms many budget folders I’ve used in the past, especially in terms of edge retention. However, the initial blade play remains a minor annoyance.

Its primary strength is its lightweight and easy portability. However, the slight blade play and initially stiff frame lock are areas for improvement. The Mantis Isosceles meets expectations for a budget-friendly EDC knife, but it doesn’t exceed them.

The handle’s ergonomics are decent, though the smooth 420J2 steel can become slippery when wet. There is a slight learning curve associated with disengaging the frame lock, particularly for those unfamiliar with this locking mechanism.
