Please pardon the shameful sales pitch - Rock Jumper

FYI, You might also keep another variable in mind when discussing edge length; serrations are in fact a longer cutting edge in a shorter distance.

Hey SubMicron,

I would be curious as to why you would be dismissive of VG-10 haveing never owned a sample?

Well, I guess the simple answer to that is because I was being an ignorant, noob, steel snob.

It's easy to get caught up trying to stack rank steels against each other, decide on a certain threshold of minimum performance, and then exclusively stick to steels at or above that level.

I suppose my paradigm is shifting.

Focusing exclusively on how much wear resistance or how much edge stability a knife has, misses a lot of the finer points and also the main question.

It's nice to have task oriented knives in kitchen drawers, work benches at home, and among the tools at work... which leads to the primary question: It's a tool, what can it be used for?

To me a K390 Dragonfly is a completely different tool than a VG10 Dragonfly, especially if one has a different blade design. Even without the Wharncliffe variable, they're each better suited to different facets of my life.

I'm sold on the superior cutting ability of serrations. Their ability to separate material for a longer period of time is undeniable.

I still do not own serrations on a Spyderco. As my freehand sharpening skills on serrations continues to develop, I've been considering getting one in the coming months.

What's your opinion of K390 serrations versus H1 serrations? I own both steels but in a plain edge. Which will cut more?

The concept of K390's toothy micro serrations stacked on top of large serrations is interesting but maybe H1 has an advantage that I dont understand?
 
Hi SubMicron,

On the the K390 serrations, I won't know for sure until we get some production pieces to test The one I tested was a proto and I was just trying to see if they would break under hard use, which they didn't.

Funny how we change views and values with new information. I remember when edge/handle ratios were important to me, as well a number of other thoughts that changed over the years for me.

One of the things I learned was not to say "This is best", as it robs me of experiencing the others. Kind of like selecting the prettiest girl or guy in class when in school.

That's how I came up with "All good, just different".

Just noticed that these are in stock GPK and couldn't resist the plain edge version.

Should make for a fantastic folder for hiking. :)
 
Rock Jumper arrived from the factory and I definitely like the feel.
It feels like a Wharny Delica that went to the gym and pumped some iron.

I really like mine. The action is incredible for a back lock and the beefier handle and blade stock give it some much needed girth. Don;t get me wrong, I'm still a big fan of teh Wharnie Delica but the Rock Jumper just gives more capability without sacrificing (much) the sliceyness of the Delica. It's like the Stretch and Wharnie Delica had a baby. Hope Jazz picked one up. He'll love it.
 
The handle comparison in this picture led me to buy a Rock Jumper. I’ve come to really dislike the Delica because of the skinny, squirmy handle. The RJ handle doesn’t disappoint. And the FRN is grippier than any other FRN Spyderco I’ve had. It’s the opposite of whatever they did on the Para 3 LW to make it so slick.

I had decided not to buy a Rock Jumper because it lacked a Boye dent. The dent is (almost) mandatory for me as a thumb index when closing one-handed. On my Native 5 G10, also without a dent, the lock bar has to be pushed all the way down into the recess of the handle to release the blade, so you can’t even cut in a Boye dent if you want one. It’s the reason I don’t carry that knife anymore.

On the Rock Jumper, the lock bar only goes in about 1/4 the depth of the recess before the blade releases. There’s plenty of extra travel clearance to allow adding a dent.

Once the dent is fixed, the only sour spot left on the knife is lack of jimping on the thumb ramp, but that’s minor. Otherwise, this design really sings.

VG-10 is a steel i really like. But i go for steels that score well on the edge retention, hardness, corrosion resistance, ease of sharpening diamond chart. I find if all four are within a 5-8 rating(so it looks like a diamond) i will buy it. 9-10 on the edge retention and a 1-2 on corrosion and sharpening(basically a triangle)is a no go. I love S30V but i think VG-10 is slightly better if not very close if you go by the numbers.
