wrote: And my kitchen-knife sharpening technique *still* doesn't work on pocket knives. About 3 years ago, in a fit of temporary insanity, I decided that I needed yet another hobby. I chose knife sharpening with plans to later get into knife making. The reason you're having problems is that the bevel angle and grind type (flat grind, hollow grind, convex grind, compound, etc) http://blog.batteryjunction.com/wp-content/uploads/knife-grinds-selection.jpg varies with the type of knife. There are also a wide variety of kitchen knife sharpening devices that are very good at destroying a knife edge. No single sharpening contrivance will work for all these types of edges. There are also a wide variety of complex and exotic methods of sharpening found on the internet and in YouTube videos that are probably suitable if you want to perform surgery with the knife, but are much too complexicated for ordinary kitchen knives. I had to learn all this the hard way, after wasting money on a Harbor Freight 1x30" belt sander, bevel jig, multiple belts, various whetstones, surface block, sandpaper selection, leather strop, etc. I already had an inspection microscope, but it too proved useless. After 2 years of destroying everything that I touched, I eventually achieved enlightenment and settled on using sandpaper for the rough cutting, water whetstones for polishing the edge, and an old leather belt for breaking off the inevitable burr. I'm not knowledgeable enough to offer classes in knife sharpening, but I can offer one item of acquired wisdom. It's much easier to sharpen a knife on whatever device was originally used to produce the necessary beveled edge, than it is to change the bevel angle or type of grind. If you can get it sharp the first time, it's quite easy to keep it sharp. The means you'll need to sharpen every knife you own at least once as if you are creating new beveled edge. Plan on practicing with junk knives. I raided the local thrift shops and flea markets where I bought a rather motley collection of $1/ea used knives upon which to practice. Good luck. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Apparently someone that posts here as I remember the implication and sharp drills were only found in machine shops :-) That would be me. Please don't rub it in. I've had plenty of instruction and practice, but drill sharpening is one skill that I haven't managed to learn. I gave up long ago. I currently prefer to drag a box of dull drills to my various machinist friends for sharpening (usually in trade for fixing their machines, CAD systems, computahs, etc). -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

IIRC, at one time Quakers building wooden boats/ships used square pegs in round holes because that'd lock the peg more securely. Cheers I don't think that was solely a Quaker practice as I've heard of the practice . I believe that in the clipper ship era tree nails (trunnels) that were not rounded were sometimes used. .. -- cheers, John B. |

If it tastes the same as what his mother made it's good, no matter that his mother might have been the worst cook in the county.

I haven't eaten a sausage since :-( -- cheers, John B. |

My father's older brother was crippled - had polio when he was a senior in high school. Being a typical New England family he expected to work and because he couldn't get around he started filing saws - this was back in the days when carpenters used hand saws - and I remember him filing one tooth at a time until he worked all the way down the saw blade and then flipping the saw in the vise and starting back. I asked him once about some sort of grinding machine and he said that yes, he had tried that but hand filing was better. I don't expect that you can get that sort of hand work in the U.S. any more... nor over here either. -- cheers, John B. |

Since almost no one mounts a bottle cage in that way I don't think that a double-blind, peer-reviewed study on hose clamps would accomplish a whole lot, but you should contact UCSC and see if they can find a doctoral candidate to conduct such a study. But I have no doubt that if such a study were ever conducted that it would be attacked with claims that hose clamps used on gardening hoses pose a much bigger danger but were ignored by the study. Or perhaps it would be someone falling out of bed onto a hose clamp that had been dropped. |

The is some sort of theory, "Occam's Razor" I believe, that says that the simplest solution is likely to be correct ? The thing about Occam’s Razor that is often overlooked is that it’s referring to the simplest SOLUTION, not the simplest hair brained scheme. A correlation might be "do it the simple way and you won't get hurt". Just stick the damned bottle in your pocket :-) -- cheers, John B. -- duane |
