When I recd the Difensa and leather sheath I was very happy with the quality of both. I had to return both only because I wanted a knife I could carry on a daily basis and it was too big. I have request an exchange for the Trout and match leather sheath. Customer service was great! The exchange request was made with no issues and now I am waiting for them to receive the Difensa and send me the Trout.
This is my second Spartan fixed blade and won’t be my last. I can honestly say it would be the first knife I’d grab for any trek into the woods. The Harsey handles always fit extremely well into the hand with no hotspots. The fit and finish is spot on from Spartan. It’s got good weight and so far has held an edge very nicely with moderate to heavy use in the 3 outings I’ve used it on. Can’t recommend this knife enough.
The good and the great: handles are perfectly sculpted, one of the most comfortable knives to hold in hand. Ergonomics are outstanding. Weight is perfectly balanced, blade geometry and design is excellent. Jimping on top is grippy and perfect, no hot spots. Sheath is top quality. Less than great: not shaving sharp out of the box. Slicing paper it was a bit toothy/gritty. I had to run over a strop a few times and that smoothed it out and it’s nice and slicey now.
Very happy with this knife , top quality , fast shipping to NEW Zealand ,

This is a great knife. Looks very good, sharp and is well balanced. The grip is also very well made.
I’ve learned not to use odd characters in my reviews to avoid strange symbol translations. As for the Harsey Difensa, it is my very favorite knife in my large collection. It’s my number one “go to” knife for any job or any situation that I may encounter. The Difensa is extremely strong, very sharp, balanced, and well crafted. The quality and blade material are outstanding in every way. It holds an edge well. The Micarta handle is very confortable and provides for a powerful grip of the knife. I finally had the opportunity to purchase this knife with a black blade, black Micarta handle, and with a black Kydex shealth. What’s nice is that the Kydex sheath doesn’t scratch the black finish on the blade like it does on my Spartan Horkos knife. I really don’t care either way about the scratches, but I thought I would mention it. The Kydex sheath provides for a tight retention of the knife, yet it’s very easy to draw the knife when needed. The knife is easy to use, and it holds up extremely well when batoning wood, cutting material, in prying situations, and even in digging. It is a “a must have” for any survival or self-defense situation. Though it’s weight is not as light as some may like, it’s strong usefulness outweighs that notion. As a former military veteran and law enforcement officer, the Difensa, to me, is among the best knives on the market for survival. I would highly recommend the Difensa for a superior, all-around survival tool. It’s price is high, but its usefulness outweighs the price. William Harsey did it right in his design of the Difensa. Of course, this is all my opinion.
I love the knife and I don't know what could be reproached to it. Personnally I consider it perfect. However, the kydex sheath is soooo tight that I had great difficulty to take the knife out of it. After removing some plastic with a Dremel tool, it is better. However, I now intend to buy the leather sheath. To conclude : go for the knife, but if you are not as strong as Schwarzenegger, forget about the kydex sheath.
