HAP40 vs pineapple!

There's not a lot of hard data out there on HAP40. I love Spyderco and this subforum. I've gained a lot from this place, so I'd like to give something back, even if it is rudimentary.

So, sorry SpongeBob, but it's time to put my new Delica to the test.

At this point, the only thing my Delica has cut is paper, which, with its very well ground factory edge, it has done with great aplomb.

I got a little carried away after slicing the top off. It was just so much fun!

I decided a great test of the edge would be to push cut the pineapple in half, from top to bottom. While of course it hit a snag or two (this is a tough fruit), it was pretty easy.

Here we can see that a patina has already started to develop after some more slicing.

While not the ideal knife for the job due to its small size, it's still just too easy!

Behold the Delica, mighty slayer of pineapples!

I tried to get some good lighting after slicing up that pineapple to display the lovely patina that's formed. While I didn't baby the Delica, I washed it with soap and water after the test, since it was covered in pineapple guts. The patina is lighter, but formed a good bit quicker than the one on my Super Blue Endura...though its patina was instead deliberately formed by sticking it in an orange.

Next to her big brother for comparison...

After this test, the Delica was still plenty sharp despite the patina covering (and thus dulling) the edge a good bit.

Soon after I took that last picture, I touched the Delica up on the Sharpmaker and used a honing rod on it in order to get the patina off the edge and get it back to factory sharpness (which was insane, if that wasn't already clear). HAP40 seems to be a little more difficult to work with than Super Blue in that respect (read: not difficult at all really), but I managed just fine. SUS410 seems to act a lot like 420J1 regarding how it takes fingerprints, scuffs, and the like, though it's slightly more difficult to keep clean.

Final thoughts: I like HAP40, and you're missing out if you don't pick one of these sprint runs up. It seems to be able to take a crazy edge without too much difficulty, and that burnt orange is a beautiful color.

If I could go back in time and tell myself a month ago anything, it would be, "Why don't you have a Delica yet, you numbskull!?!" I've become a big fan of the Delica model on the whole after using it. It's more than just a scaled down Endura. Mine is going to see a lot of pocket time (though I'll hardly notice it, takes up very little space and is so lightweight!). What an awesome little knife! Thank you, Spyderco and Mr. Glesser, for putting such a lovely little tool on the market! :)

What a fun write up! I love pineapple and my HAP 40 Delica too! The part about the numbskull made me laugh. Me too, I've had knives for many years, but only just now tried a Delica. What in the world was I waiting for?! This sprint run rocks!

Aplomb? I thought it was a pineapple...



:D
:o

Great writeup, though! I've been tempted by the HAP40 sprints. I'm missing my FRN Endura. Something about its pure-function design. And to get one with M4-ish steel would be sweet.
 
Kwon Kwang, thanks for taking the time to document your experience with this steel/knife combo and share it with us here. Nice pictures too. I can see the effect of the acids on the blade pretty easily.

Threads like this are why I come here.

I use to avoid cutting and slicing citrus fruits with my EDC knives because I thought the acidic properties of such fruits could potentially harm the steel (especially the pivots and hard to reach areas). Just a dash of water rinse got rid of the stuff huh? Good to know, thanks.
 
He cuts with aplomb

and gives just enough
info for us to rant.
 
Nice write up and thank you. I've been debating on buying a Hap40. I believe I'm going to wait on the Dragonfly
 
Cool thread! Now I'm craving for some pineapple! :D

Can't wait for the Stretch to drop!




Interesting that you feel the HAP40 formed a patina quicker than Super Blue. Seems the opposite in my uses... maybe it depends a little bit on what you cut.
 
Nice pics, thanks! I just love the HAP40 Delica, so thin and slicey. The steel is very impressive too. I dare say I like it more than the Super Blue sprints.
