Me too, that was somewhat of a private joke.

That damn pointy thing can be used for a no. of things, including poking yourself.

It's not a Crocodile Dundee "That's a knife" knife. Very light and compact. Slips in any shorts pocket. My wife carries one too.

Whenever I see it on sale for $10 at West, I buy another figuring it's some pricing mistake that West will eventually fix. I think I've bought 10 of them so far.
The straight blade or serrated blade?

Check out this video of the Boye, not just how fast it cuts but how much it cuts.

Re: Rigging Knives -- Straight vs Serrated?

I've had an Ibberson straight bladed folder since '71 or '72. It can be made razor sharp with a few strokes on an Arkansas oil stone. I've used it hundreds of times and abused it a few also. I like fine tools and I can appreciate some of the awe inspiring knives mentioned here but I'll stick with my Ibberson.

Re: Rigging Knives -- Straight vs Serrated?

"I'm with the

"If you can't baffle them with your billiance, befuddle them with your bullsh*t" crowd."
(Carstenb)

And on that note:

I'm seeing lots of other knife guys on here talking about blades, so I won't even go into blade choices here. And that's largely a personal thing with knife fanatics, anyhow, isn't it.. But I've been a knife sharpness nazi since I was a cub scout. I can't stand dull knives. Friends and family like for me to visit because they know with half an excuse I'll leave every knife in the kitchen with a razor edge. I use stones, diamond steels, butcher steel...ceramic coffee cup bottoms. Leather strops. glass tile. The instep of a boot.

And it seems to me that the original poster here is having a problem with the frustrations of keeping his knives sharp. I've done a little study for my own education, after receiving a very fine set of kitchen knives for Christmas. I used a 10X jewelers loop to very closely examine the edges of several good german steel knives (Germans, Finns, and Japanese make the best knives in my experience) I used fine stones, several shapes of diamond dust covered steels ( triangular, cylindrical, flat surfaces vs small contact point) and I bought several commercial hand held sharpening devices to test, too.

My opinions, based upon this informal testing program, are that for someone who just wants a really sharp knife quickly without having to learn any technique or memorize angles is to buy two little sharpeners at the sporting goods/fishing tackle store. Get one that has small carbon steel cutters preset at an angle. You draw the knife through it and the carbon steel cutters shape and shave the angle and will establish a really sharp edge with just a few strokes. You've got it right when you can feel the steel shavings coming off when you pull a dull knife thru it.

THEN, bufy one of the little cheapo red plastic sharpening things with two white ceramic coated rods in it at the same angle as the carbon cutter. You can tell by eyeballing it. After pulling your dull knife through the carbon steel cutter about three or four times, pull it through the ceramic cutter about the same number of times. The only technique you need to remember is to hold the blade centered and the same each stroke. So in something like ten seconds you can have a razor sharp knife.

Only way I know to sharpen the serrated edges is to use one of the tapered cylindrical diamond steels on the inside of the serrations, the inside curves. And use a flat stone to keep th opposite side of the serrated edge flat with no bevel and no burrs.

Knife guys know about edge shapes and tempering and folding and various steels and even various grades of stainless. I'll hand sharpen a scalpel differently than a chisel or machete, and the 3 blades on my whittler are all different edges, but hey, that's just me.

Don't get me started on multitools....

Naah, here ya go. I found you the perfect sharpener for a non-knife guy:

This will do your serrations too.

Re: Rigging Knives -- Straight vs Serrated?

Actually I have a sharpening stick both on the boat and in my kitchen. I give any knife I pick up a couple of quick strokes before I use it and it is always razor sharp. Once or twice a year, or if the stick won't hone it, I'll sharpen on a stone.

It all depends on how you treat your knife too - it should always be in a sheath never tossed in a drawer with other cutlery.

Never put one in a dishwater - when you washit, always dry it carefully.

Re: Rigging Knives -- Straight vs Serrated?

I have been using Moras for years. Crazy sharp and you can get them for $10 at a fisheries supply. They will cut anything and won't break your heart when you drop it overboard.

Re: Rigging Knives -- Straight vs Serrated?

A serrated knife doesn't really cut, it shreds. They can be very good at that. Serrated kitchen knives exist so they can rip through a hard bread crust, without squashing down and crushing a soft (interior) loaf. Or ripping through a tough tomato skin within squashing out the soft interior.


But aside from ripping hard crusts...a sharp plain blade is easier to maintain and will always cut cleaner. If you simply press it against a taught line, the line will part. No ripping or sawing needed. Smooth cuts in fabric, too.


Serrated teeth, being curved, usually have some portion that is still sharp from being unused well after the points have been worn. You need a small circular diamond file (etc) to put a sharp edge back on the entire edge of each serration, kind of like sharpening a chain saw. (What, you don't have one onboard?)


With a good flat blade, if you get in the habit of stroking it with a ceramic or diamond steel every time you use it (or pass the galley after using it?) you don't need to do any heavy sharpening for really long periods. Like brushing your teeth, to avoid dental visits.


http://smile.amazon.com/gp/product/B...?ie=UTF8&psc=1


There are plenty of ceramic sharpeners, like this inexpensive one, available. Once you have a proper edge on a straight knife, you can just pick this up, swipe the blade a few times, and keep it razor sharp with no effort.


I'd have a great deal more faith in your father's knife than whatever the Chinese one claims to be made of. Serrations can hide a lot of cheap alloys. Although some of the new (and damned expen$ive) knife alloy$ are supposed to put the traditional ones, like 440c, to shame.


Any restaurant supply house will put a good edge on any straight blade for about two bucks while you wait, if you want a shortcut.

Re: Rigging Knives -- Straight vs Serrated?

If you pick up a line on your wheel. Painter, wharp, whatever go to the galley and get a serrated blade kitchen knife. You know the one for the roast.


That is not being a wise ass.

Re: Rigging Knives -- Straight vs Serrated?

First of all, thank you Cadence for you knife sharpener suggestion; I've been using an Arkansas stone and steel, but will give your sharpener a try. Love that Amazon Prime!

If you look at the pictures of the West Marine rigging knife and the twice as expensive SOG, you will see that they appear identical. Seems like a pretty good deal to me, especially when West Marine puts them on sale.
