Endura 4 Super Blue Sprint

Supercharge the cutting performance of the Endura4 Lightweight format with this extraordinary limited-edition Sprint run featuring Aogami Super Blue blade steel. Manufactured by one of Japan’s leading steel manufacturers, Hitachi Metals Ltd., Aogami Super Blue combines the same high quality iron sand that has been used for centuries to make Japanese swords with state-of-the-art alloys. The result is a steel capable of extreme sharpness and edge retention. The full-flat-ground blade of the Endura4 Super Blue actually consists of a Super Blue core sandwiched between layers of 420J1 stainless. It is mated to a lightweight handle featuring skeletonized stainless steel liners, injection-molded fiberglass-reinforced-nylon scales, and a four-position clip that supports left and right-side tip-up or tip-down carry. Like all Enduras, this knife’s Trademark Round Hole™ and sturdy back lock mechanism provide ambidextrous, one-handed operation.

Note: Aogami Super Blue is a high-performance, high-carbon steel and is not stainless. It requires proper and diligent maintenance to keep it corrosion-free. Spyderco is not responsible for the corrosion or pitting of a high-carbon blade.

    Fantastic knife at a great price!

    The knife arrived quickly and was exactly what I was expecting. It is a spyderco endura 4 aogami super blue laminate sprint run. The build quality on the knife is exceptional, and this has been the case on all spyderco products I have purchased so far. One thing to note is that this knife requires special care as the core if the laminate is not a stainless steel and will rust if not cared for. Over time the non stainless portion of the blade will develop a patina, this is normal and not something wrong with the knife. This is one of the best steels that I have gotten to use. It is very high carbon, sharpens very easily, and holds its own against a lot of the more modern powder metallurgy steels on the market. I have some other spydercos in zdp189, and another sprint run in hap40. I am still figuring out the best way to sharpen the zdp-189 which is a bit tricky, but compared to that this super blue is very easy to sharpen and takes a very fine edge. It's edge retention seems to be slightly behind zdp-189, but that is just anecdotal, I have no data to back that up. If you want a very high performing knife and aren't scared away by non stainless steel this is definitely a knife and a steel to consider.
