With some reluctance, I'm going to post my original review below, along with some comments I've inserted, {italicized, and in brackets}, to hopefully clarify things and take the edge off a few of the remarks I made.
VG-10 Calypso Jr.—Review
Background: I recently acquired a gray FRN PE VG-10 Calypso Jr., which was replaced by Spyderco under warranty (see later posts in [thread=268894]this thread[/thread], if interested.) Having had some time now to work with the knife, I felt a brief review might be of interest.
Comparisons between the original Calypso Jr. I'd received and the replacement bear out the fact that there was indeed something wrong with the steel in the first knife. From the factory, the first knife required 5-5.5 pounds of force to push cut unsupported .080" nylon monofilament line (reference to earlier discussion found [thread=305456]here)[/thread] while the replacement knife required only about 4.5 pounds. Due to problems with microchipping, the first knife could not be satisfactorily sharpened; the replacement knife, however, responded readily to finish sharpening with fine ceramic and stropping on leather loaded with CrO, after which only 3.5-4 pounds of force was required to push cut the unsupported nylon line—the best performance obtained to that point from any knife I've tested using this method.
Preliminary, informal testing of the new knife finds edge retention to be extremely good, if not excellent. After cutting about 12 yards of recycled cardboard stock—a material prized for it's consistent ability to dull a fine edge on lesser steels after cutting only a few feet (also prized for the excellent bottled beer that comes packaged in it)—the blade would still cleanly shave arm hair, and performed other, routine cutting tasks as though just freshly sharpened.
Despite the more-than-satisfactory sharpness of the Calypso Jr., I had noticed early on that the edge bevel wasn't particularly consistent, either from left to right or along its length. Being somewhat particular about these things, and since it was only as a result of having attempted a full sharpening of the original knife that I was able to identify a serious problem with the blade steel, I decided to reprofile the edge bevel of the new knife to ~12°/side.
It turned out that the bevel on the right side of the blade was already just about 12°, and had been ground quite shallow from the factory. The left side bevel was far less regular, but overall close to Spyderco's stated target of 17°, and, having been cut much deeper, resulted in this being a more substantial reprofiling job than it probably should have been. For my own reference I like to see how a particular steel works on a medium India oilstone, and while the VG-10 wasn't particularly hard to work, most of the reprofiling was done with diamond media, which went quite quickly. The primary edge bevel was then finished up on medium India, with it being worth noting that the VG-10 took an unusually fine and uniform finish.
A light microbevel of 17°/side was then applied with fine ceramic. When examined under magnification, no microchipping was found as had been observed during sharpening with the knife returned to Spyderco. Following a light stropping, the knife was tested for sharpness, severing the unsupported nylon line with a mere 3 pounds and change of force—better than I'd honestly expected, given that a new double edged razor blade requires about 2 pounds.
In practical use, the Calypso Jr. is clearly an effective tool for a variety of light cutting tasks such as many people are likely to find in the home or modern work environment. This, IMO, can be attributed almost exclusively to the high performance grind and blade geometry. Further work with the knife and subsequent examination reveals some minimal tendency towards microchipping of the edge, but with little perceptible degradation of cutting performance in actual use noted thus far as a result.
{Here's where I feel my judgment may have been colored by other factors:}
I was initially impressed by the ergonomic contours formed by the blade and handle for placement of thumb and index finger, the elegance of this design and how the contours work harmoniously when the knife is closed. Despite this interesting feature, however, I don't particularly care for the ergonomics of the knife. With the lock having a small amount of vertical play, the thumb and index finger are positioned to feel the blade squirming relative to the frame when cutting, which does not inspire a sense of great confidence in the overall strength and construction of the knife. Too, even as inexpensive FRN folders go, the Calypso Jr.'s handle has a bit of a cheap feel. The fishscale texture on the sides of the handle seems to have little functional value, as purchase is mostly achieved on the edges of the handle and in the aforementioned "squirmy" thumb and index finger recesses. It seems clear that the designer(s) sought to optimize the knife for holding in one position only, that being a "normal" grip with the thumb on the ramp area on top of the blade. As a result, other grip positions are mostly uncomfortable and not particularly workable.
{What's particularly ironic here is that I am unusually fond of lightweight FRN folders; in fact, since I was a kid, it seems like my taste in pocket knives has always been away from the thick, heavy Boy Scout knives and Barlows I first became acquainted with, and towards the thinnest, lightest, full-sized, single locking blade folders I could find. I'm pretty sure that if the Calypso Jr. didn't have so much vertical blade play, my gut-level reaction to it would be much more favorable: I was dead serious in calling the thumb and index finger contours of this knife elegant; it's just that those same contours magnify one's awareness of any blade play.
However, having had a lot of experience with FRN folders, I do have a certain basis for comparison here, and a very good one would be the Ka-Bar Dozier series, the handle on which is exceptional (IMO) especially for a sub-$20 knife. Where the Calypso Jr. is a specialist, optimized for one particular hold, The Ka-Bar Dozier is an amazing generalist—I can hardly find a position in the hand where it doesn't feel good. The Ka-Bar feels more solid to me, I like the texture better ... and it's even got an adjustable pivot and can be fully disassembled. The Ka-Bar AUS8A, though, leaves a great deal to be desired, and I don't really care for hollow-ground blades. Thus, despite its merits, the Ka-Bar Dozier is no more than a decent, sub-$20 beater to my way of thinking. The Calypso Jr. is much more than that, although I still think it could be improved upon.}
In addition to the Calypso Jr.'s excellent blade geometry, sharpness and edge retention, other pluses are its smooth operation (replacement knife noticeably more so than the first), stiff lock spring and Boye detent to reduce risk of accidental opening, and light weight.
While it is certainly gratifying to any blade enthusiast to have a knife that can so easily obtain such a keen edge and retain it well, I find myself with extremely mixed feelings about this knife. The Calypso Jr. lacks the versatility and robustness I prefer in a knife for everyday carry and all-around use. Nor do I feel that Spyderco has executed the knife as well as they could, or should. If this knife is seriously aimed at the enthusiast market, then a higher quality handle or handle material is called for, with better overall construction and improved quality control. As it is, it's easy to surmise why this knife may not have been a commercial success for Spyderco, inasmuch as its design and construction really limit it mostly to tasks for which a simple box cutter would probably be a better choice for most people, under most circumstances.
{I know that can't sound good to those who really like the Calypso Jr., but that was my honest conclusion after reflecting upon where this knife fits in the broad scheme of things; or at least, where it would fit among the knives I own and use, in terms of function and job suitability. When I said that "a simple box cutter would probably be a better choice for most people, under most circumstances", what I was referring to was the lack of acceptance of the Calypso line in the non-enthusiast market, which I've seen discussed on the Spyderco forum. The average guy probably isn't going to have the skill needed to use a knife such as this, keep the premium steel blade sharp, and perhaps even keep from breaking it; with a box cutter, he faces none of those things, which for him may be very real problems.
I also can't see the Calypso Jr. filling some of the roles many desire from their EDCs: self-defense (though I would *hate* to be slashed with one!), cutting chores where you need a blade with more belly, or when you just have to bear down on something thick and tough in order to cut it. But this may reflect nothing more than personal prejudices, born out of my own limited experiences.
I think it's fair to state, too, that my thoughts here have been colored by my adoption of the BK11 as an EDC knife during this same time. I'd never realized how much I would appreciate a robust, hard use little knife like this. If I could only carry one knife with about a 3" blade, and had no way of knowing what I might be doing with it in advance, there's no question which I would choose.
But that's not a valid criticism of any other knife, particularly not a knife like the Calypso Jr., which I see as a specialized—and yes, I would say, a very refined—design. I only wish I had received better built examples of this knife, in order that I might fully appreciate all it has to offer, as many very knowledgeable knife enthusiasts obviously have.}
