In 1990 Spyderco shook things up by introducing two knives, the Delica and Endura. First of their kind on the market, both folders opened up the knife market to lightweight performance, one-hand open pocketknives that just about everyone could afford. They settled as their top two bestsellers and their improvement hasn't slowed since.

Spyderco have always taken great pride in their efforts to push the envelope of performance by offering exotic blade steels in their knives. With that spirit in mind, they are proud to offer the Delica 4 Lightweight with a blade crafted from K390.

Manufactured by Böhler-Uddeholm, K390 MICROCLEAN® is a state-of-the-art cold work tool steel produced by the particle metallurgy process. Its advanced alloy mix was specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. Despite its toughness, its exceptionally fine, homogeneous microstructure also makes it readily machinable and easy to heat treat.

Collectively, these qualities make K390 an outstanding blade material for true steel connoisseurs.

    Tool steel!

    Posted by MC Hammer's Leather Notebook on 3rd Mar 2023

    I have one of these and love it. I am a fan of tool steels anyway, a bit of a D2 addict. However, the K390 is really nice. I'd love to see a UKPK in K390 that I could EDC. This Delica showcases the steel nicely- it's hard and takes an edge like a lightsaber.. and keeps it. It's not actually too hard to sharpen, a Sharpmaker with white rods of different grits will do the job- just don't expect a pristine edge in seconds from wiping it on a kerbstone. This is a practical knife, for using- it's not pretty, it's all business. My only slight niggle is that the design of the pocket clip makes it sit a little high- aftermarket clips can solve this.

    K390 Micro Clean loves to be edgy

    I love K390, it’s my favourite tool steel next to good old 01 how ever a lot of knife makers are not heat treating O1 properly as it’s a very old tool steel and takes a little more effort to coax the carbide homogenisation and carbon face-centred-cubic (gamma-iron) form into martensite and people make the mistake of trysting it like a simple low carbon steel which leads me onto K390 and at work we love this stuff, we call it O1 on mega steroids in fact it’s more closer to a HSS than a die and stamping steel. We use it for all sorts of things at work. We’ve used this stuff as scraper blades on hand flattening work bench’s and it blows O1,O2,O6 and 7 all of the “W” range and D range in fact in terms of alloying bad performance it’s closer to high speed steels and it holds its edge for longer because it’s tougher than HSS and we find it easy to machine on a mill to make the scraper blades and it’s very easy to heat treat and we usually go for 63-64 HRC. It has a million and one uses in a machine shop how ever it’s far far more expensive than O1 but lasts far far longer and does not chip anywhere near O1 as it’s tough almost in like the S range of steels but with and edge that lasts for ages, I’ve also got to correct the errors when people say Particle metallurgy but Bohler uses powder metallurgy and it’s methods they way they make it are different than crucible or carpenter. So overall in essence what I’m saying is that K390 is the best state of the art tool steel for knives available today and you should buy it because it is very hard to get old of spyderco knives in K390 because every one buys them up, because of its performance and you’ll see why when you get yours but remember it’s a tool steel extremely high in carbon so a coating of oil must be kept on the knife if you do not want moisture and rust to form on the steel. Look after your tools and they will look after you........and your bank account

    I have owned a Delica in VG-10 for some time and it has been one of my favorite knives. It was my go to for my fishing trips. I l enjoy it so much I thought I would honor it by purchasing an upgraded version. The K390 blade is wonderful, the buil

    Poor build quality, unacceptable blade movement.

    K390 Delica

    Posted by Londinium Armoury on 4th Nov 2020

    Why did I spend £150 on a Delica, because I'm crazy, and so are you, so get it you know you want to.
