I haven’t made it into the backcountry with it yet so these are my first impressions. I’m 47 years old and have had a knife on my hip practically my whole life. That being said, this is by far my favourite knife of all time. I won’t go into long details about the lines, weight, balance, and grip, I’ll simply tell you this knife feels amazing in your hands! It really just becomes an extension of yourself. It feels like it has some life to it, it hums. Why 4 and not 5 stars then? What could have been a perfect knife (and at this price point it damn well should be) was ruined by how poorly the knife’s edge/grind was applied. From tip to heel you’ll get 2mm at one end thinning down to 1mm at the other. This unevenness flips on the reverse side. The result is an asymmetrical tip that I will eventually have to balance out. Truly disappointing in that regard but if I had to leave my house today, and was only allowed to keep one of my personal possessions, I’d take my Difensa.

About a week after the knife arrived I was on a plane to teach a Jungle survival course. This was going to be a great test of the blade. The Spartan Harsey Difensa knife perform exceptionally well on the jungle tasks. Including shelter construction, bamboo fire saw, snares and firewood gathering. The knife fits my hand which made easy to cut and chop on hardwoods and softwood as well as Bamboo. I have used 100’s of knives in my career and the Harsey Difensa knife is the winner. Exceptionally sharp and ready for any tasks.
Great fit and finish. All details in this knife mean expert craftsmanship.
Absolutely amazing. This is a totally bad ass knife! Excellent high quality good old fashioned MADE IN THE USA!!!
This is officially me KNOIFE, gonna stow it in my plate carrier and got a Enyo to wear as EDC and pop on me battle belt if needed. Bless Spartan Blades and BLESS THE USA. Defend America.
just recieved this knife. Its more beautiful in person than the pictures can do it justice. Well worth the price.
I couldn’t be any happier with the quality of their work or with their customer service.
Ordered over a weekend...had tracking by Monday morning. Can't say enough good things about Spartan Blades customer service. They even left a hand written note thanking me for my business; nice touch. I'll be buying at least one more Harsey from them in the near term. In terms of the Difensa....exactly the quality you'd expect.
This is my first high quality knife and I have to say... It's surpassed anything I could have expected. I'm extremely happy with it! I've got to say these guys make a top quality knife and this will not be my last purchase with them. Thanks Spartan Blades!
