Today I received a serrated Magnacut UKPK Salt!!!

Hi Cjk,

I've been carrying mine for a few days now. Quite the tool. Light and convenient with a great deal of cutting power. I was thinking that if we had a definition of CutPower/weight, it would rate very high. (Like Horsepower/weight).

I am happy for you. That is a great knife. Now, if @sal would make that same knife in black FRN I'd be even happier.

Hi Doc,

I agree that it should e an option, and might even be in-the-works. But I'll put a bug in Management's ear for both of us.

I purchased a yellow SE Lc200n Ukpk this past December. I figured as soon as I bought the old one, the new Magnacut SE one would come out soon after and it’s finally here!! Definitely under 10 pounds per horsepower.

I would consider the upcoming 15V lil Native lightweight to be potentially worthy of being in that club.
The ZDP-189 and K390 Dragonflies and the K390 Stretch 2 XL also leap to mind. I should probably create a new thread.

Hi Cjk,

The concept of "CutPower"/weight would be a nice tool for the knife industry. I thought about starting a thread to see if our folks here can come up with a definition, or formula, but thought it might be too pedantic. I decided on just mentioning it for the UK model as that was my thought when using the knife.

I got to handle Jason's at the SFO, and it's definitely a great addition to the lineup. Simple, light, and highly useful. One could carry both PE and SE and never really be outgunned in the cutting dept for nearly all tasks.

I’ve been waiting on my preorder from knife center since they first got revealed and it has just been delivered to my home in Singapore today I bought it specifically as food prep knife while backpacking (In my misspent youth I accidentally cross contaminated my food by using a single knife for all tasks while out in the mountains and that was the kind of eventful I don’t ever want to experience again). The UKPK has to be the perfect knife for that duty - ultra slim, light, cuts like an absolute monster in either configuration, can be used as a redundancy in case you lose your main fixed blade, looks non-threatening enough to use in public in the UK. Fantastic! Can’t wait to unpack it when I get back from Australia.

Picked up a factory 2nd serrated lc200n UKPK around this time last year on a lark from a very reasonably priced eBay seller. I just can't stop myself from carrying it. All the benefits of the UKPK combined with all the benefits of SE, it's a perfect knife. Stoked the Magnacut version is finally trickling out in the wild.

I've been calling my amazing ffg Salt 2 SE the best "weight to performance ratio" folder I know of quite some times (basically meaning what you said better with "cutpower/weight")... but the UKPK indeed shaves off another roughly 10% of weight while offering a similar cutting edge length!

I have one in SE Magnacut coming in looking forward to it after my last SPYDERCO slip joint PITS2

While it would discount the performance of the steel, edge length / ounce would be an interesting starting point.

Okay so my UKPK is here.

First off I love the Slip Joint Detent no way you are closing on you hand. In fact this can replace the need for locks.

It is slicey but my Chaparral SE still holds the crown.

Hey Sal How about some Chappy Slip Joints SE

This is a Great knife but I am going to have to dye the scales. Just a bit too yellow when it can out yellow M&M’s

Did Spyderco change the shade of yellow on the UKPK Salt's scales? Mine is the yellow LC200N SE version, but the handle is almost more of a mustard yellow.

Jim

Yes the color is not the same and not just due to textures my camera doesn’t get it right but the UKPK is brighter and lighter the PM3 and Native chief are mustard yellow.

Hmmm any chance of a 15V UKPK? If so yeah I will buy a few.

Guys,

To me the hp/power thing has always been somewhat jacked up even on engines and motors. Being a gearhead I have always been into all that.

Where the measurement gets off is the actual power any motor or engine makes is torque. Sure the hp is in the window and was what was forever the only thing to judge the power.

Later on as technology advanced come the mathematics of putting that all on paper to graph it correctly so as to know how there was two motors with the same hp, but they could not be more different lol. Hope this makes sense as it's really hard for me to type this to where it should anyway.

The word torque come into play while all these tests started to gain popularity. You can add gear boxes to both fueled motors as well as all the electrics. You better know the torque is where the power is brought online at any rate.

I really think it would be quite applicable to apply the word torque to our different edges ability to cut something. There will need to be a standard established to zero all the variables to.

As with engines and motors, our edges have a host of things that we can change, such as the different dps, the blade finished surfaces texture and coatings now even seem to me going to come to play as well.

Where to start, jimo I can think of no better place than Spyderco, we just need to figure what is so repeatable and accurate at it and start there, least I think would be where I would begin.

Needs to be something more timely than cutting one mile of rope IMHO too. No company is going to be on board with a guy spending two days cutting rope, re-sharpen at a different dps or coating and so on.

I know there are some of y'all here that can come up with just the thing for torque to be applied to the cutting edges of our knives here fellows. Just my nickles worth on this great topic.
