I got my first Buck 500 ("\" = 1994) last week.

I have lusted over one of these for a while now, and I was pleased to score one in good (*koff* *koff*) condition.

"Good condition" is where the knife doesn't have a broken point, has an edge that can be restored, and the scratches and dings on the bolsters and scales can be buffed out.

It took me an hour to give it a decent edge, but there is still "gapping" in the edge from the nicks it had. Under magnification, it is clear it needs to travel the entire fifteen miles from here to the factory for some TLC. Restoring the edge will mean removing a bit of metal and possibly cleaning up the profile a bit afterward.

It snaps well, but there's a noticeable "rebound" when it snaps closed, and the amount of force needed to pinch it open is minimal -- I can hold the blade, flick the handle down easily, and it snaps open. Good lockup. Almost no blade play when open.

In other words, it will make a find addition to the EDC roster.

However . . .

I have now grasped something about sizing and proportions when making knives.

If you take a given knife pattern, like say the Buck 501, and you add a quarter inch to the length of the blade -- and then you increase all the other dimensions proportionately, you don't get a small increase in mass (and therefore weight), you get a large increase in mass. You hold the 501 and the 500 up next to one another. Even at a glance, the 500 is glaringly larger. A brief heft of the two tells you that the weight of the 500 is something like double that of the 501.

So I took some measurements.
*Pattern* Len Closed Len Open Blade Len Thickness Width Weight
Buck 501 3 13/16" 6 3/4" 2 3/4" 3/8" 7/8" 2.8 oz
Buck 500 4 5/16" 7 1/2" 3 1/16" 7/16" 1 3/16" 4.8 oz

Notice that the effective increase in blade length is barely over a quarter inch, less than a 10% gain, and yet the expansion in the handle size is from modest gent's to manly hands.

No single dimension of increase is particularly dramatic, but the resulting increase in mass (and weight) is almost 72%.

The net result is a knife that, frankly, is too heavy for EDC in slacks, and heavy enough to feel in your pocket when you walk in [whatever] trousers.

For comparison, the Buck 110 EcoLite -- a substantially larger knife -- weighs only 4.1 oz. The Buck 112 EcoLite -- essentially the same size as the 500 -- weighs in at 3.3 oz.

In my pocket, the magic threshold for carry is about 3.5 oz. Under 4 oz, I can carry it. From 3.5 and down, it's comfortable and goes unnoticed.

But wait, there's more . . .

I have an older 426 BuckLite. The blade style is the same as the 500, but the blade proportions are different. The blade stock is the same thickness, the 110 blade is a shade wider than the 500, but the 426's blade is 3 5/8" long, a little over a half inch longer.

The extra length of the 426 is not accompanied by exaggerations in the other blade dimensions. You get more length, but not thickness and very little width increase.

The profile of the 426 blade is elegant and balanced.

I can't escape the feeling that Buck could fill a very nice niche with a knife that fits in that place between the 501 and the 500.

Take the 501, add that quarter inch (or 3/8") to the blade, only widen the blade about 1/16", and keep the thickness the same. The resulting increase in mass (accounting for handle expansion) should only be about 25% to 30%, taking the weight to maybe 3.5 oz, maybe as high as 3.65 oz.

You have a knife that's elegantly styled, just that little big bigger for those you need (or want) that +.25" or so, and it comes in well under 4 oz. That longer, narrow blade would be right purty.

I would be tickled to carry one of those.

Of course, there's also the obvious alternative: make the 500 in an EcoLite version.

I'd carry that.

 
I carry my 500 in my watch pocket all the time and it doesn't bother me. I think the 500 or a 112 is just about right for a city knife, any smaller and I wouldn't buy one. A 110 I carry when out in the more open spaces, in it's sheath. DM
 
If I can carry a Glock 26 in my right front pocket......I guess I can carry any folding knife.

Just gotta wear manly pants.

:D
 
The complaint isn't the size of the 500, it's the weight of the thing.

Right now there's a 112 EcoLite in my RF pocket. Same size (actually slightly thicker), but noticeably lighter.

My design suggestion isn't about making a smaller knife, just a lighter one.

 
I wish Buck would make something like "this"

It sounded like you wanted something between the two, 501 and 500. To me the 500 is very correct for a city dweller to carry while walking the dog in the park or around town. Camping it could do as a bird and trout knife. Your mileage may vary. DM

You know, I must be getting rusty. Time was when I could express myself and actually make my intent understood.

The size of the 500 is fine. The weight of the 500 is not. I'm going to propose that the primary reason the 500 is not a viable retail item any more is that most people simply find it too heavy for EDC.

The design I proposed was intended to -- using the same basic materials -- achieve the blade length of the 500, keeping the same essential style, but doing it in a package that weighs less.

Yesterday's front pocket knife was a 112 EcoLite. Same size as the 500, but at only 3.3 oz carry weight. Right now I'm carrying a Vantage at 3.8 oz. The Vantage blade is longer and wider than the 500, yet the total knife weighs a full ounce less.

I was proposing a design for a narrow, but longer, blade housed in the same framework pattern as the 500, with a target weight of something like 3.5 oz.

I'm betting that re-bladed EcoLite that sitflyer pictures above weighs only about 3.4 oz. Same size as the 500 -- actually, slightly thicker -- but an ounce and a half lighter.

Lighter, when it comes to my right front pocket, is good.

 
Ok, think nothing of it. It sounds like you may like a Duke done the same manner as the 112 club knife, actually the 112 paperstone. This model has only one bolster a front the rest is paperstone making it lighter. DM
 
I think Buck is missing the boat by not offering a more elegant drop point in this size range.

I find it's not just weight. Thickness counts a lot. Suggest giving the 500 a ride for a bit. I find it's a great carrying knife as the thin profile and smooth bolsters sit nicely in the pocket. My insanely light but thicker Opinels don't carry as well. I agree completely how a small change in length makes a noticeable difference in overall size. My 500 is much bigger than my Schrade 5OT, same size as a 501.

My problem with the 500 is the lack of belly in the blade. I vastly prefer the shape of the blade in my 482.

A single bolstered 500 with a studless 482 blade and paperstone scales would get close. So would Sit's drop point ecolite. But I would a thinner version.
