The can opener: a common tool found on many pocket knives 

Thanks. Sorry for the late reply. Back issues. I try to be objective and I also try very hard to let people know my biases us front. I'm not trying to sell products, just hand out information. Glad you're enjoying the channel.

Hitch Post, several people suspect that. I’ve always wondered why it wasn’t until 1975 that Wenger was able to use the older style opener from Victorinox and why they had to buy it. Swiss law has to be some wacky stuff!

Glad you enjoyed it!

I have demonstrated using a couple in the past (not sure if all the videos are up or not). My main problem with doing these demos is you only get one chance and then you need to find another can! I can only open so many cans of tuna or beans! So many cans no longer require a can opener and I don't eat many canned vegetables. The next problem is I've never attempted using some can openers. (the old half moons and the Dogleg found on old Wengers.) These days I mainly use can openers for opening cardboard boxes and/or scoring lines.

@@KnifeChatswithTobias thank you for the response! I asked because I recently bought a 1930's Scout knife with the half moon opener and it seems pretty inconvenient to use. I suppose if you were going to make a video like that you could make a mixed bean salad since it requires a lot of cans to be opened. If the cans have pull tabs you could probably just use the oldrr can openers to attack the bottom of the can since they're essentially glorified mini-knives.

Thanks. I've got a playlist for my Traditional Pattern videos. You may find it helpful. ru-vid.com/group/PLJLlvIi3Io4yN2OGgJZ4v_OZ6MAYEJfyP

Funny you should mention that. I rarely if ever use a can opener on a knife. I use my P-38 as well. Probably the best portable can opener ever invented! Thanks for dropping by

Why? A modern can opener just works much better. And if you really just like to do things differently, at least get a P-50, it is just like the 38 but bigger and so it is a lot easier to use, more leverage, etc. If you are just keeping it in your kitchen and opening cans for cooking, for it don't need a tiny little thing like a P-38, which was designed to be used to open a could cans and thrown away. It is just making life twice as hard as it needs to me me be if you have more than one or two cans to open. And the pivots wear out and won't "grab" the rim after a few dozen cans.

Thanks. Glad you enjoyed it!

Glad you enjoyed it!

Sorry you can’t make it.

Thanks. I've been researching can opener on knives for some time. I'm sure I'll be doing another one in the future as I find out more about about the pre-WWII can openers. Unfortunately so much of the information is very murky. Its very difficult finding some of the patent information as I suspect they may have been first patented in England or Germany.

Yooper Trooper, I’m pretty sure axis lock is the TM for the Benchmade version of the lock. If so, they can definitely sue for the use of the name.

It basically cuts the same way as the Wenger Dogleg can opener. Fairly awkward and not the safest in the world: I’ll try and revisit these can openers with demos when I get some cans to open. But this video on the dogleg will give you the general idea: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fOpAHLDI04A.html

I will check it out ASAP. Love the Trail Master. I'm betting you have a pre-WWII one!

Most can openers won't open a can? They are harder to use? How do you define "works better" as far as can openers go? I have never had a problem with modern can openers. I had one 97¢ one I got at Walmart because I liked how basic it was. It didn't work, in it is just bent. So I went back and got a $10 one, which works just fine, it opens cans with ease with a slight squeeze and a few easy turns of a knob. How does your old fashioned blade designed to open soft tin "work better" than that? I can believe that you _prefer_ to use your old style opener, that you find it satisfying, you like to be different, you like a little challenge, you like to know you have a lost skill. But don't try to convince me it "works better", because I don't buy it.

Food Grade Mineral oil; you can find it at the drug store. All I use

Mineral oil, dude. That is all you should need. I guarantee that is all their expensive "multi tool oil" is. Because they know people are stupid enough to buy it. People who go out and buy a $200 gadget and see special oil marketed for it will often just buy both without question. You don't even need mineral oil, any oil will work, just some vegetable oils can gum things up. But it is better than no oil if you have a carbon steel blade. If you don't, you don't really need to oil it. Maybe a drop on the pivots once a year. Not that oil will hurt anything at all. Even WD40, 10W-30, gun oil, all fine. Just not great if you are going to cut up any food with it (although I know plenty of people who have eaten food with oily knives or hands and never gotten sick or died so I think people stress over it to much).

Yep! Just pound on your can with a hammer and chisel! LOL

@@KnifeChatswithTobias Supposedly the first can opener came only 50 years after the start of the use of caned food.

BD H, it truly is just a minor rant. But it all ties together.

Perhaps they do it 'cuz folks just keep *_buying_* 'em...?! China's always been easy to bash, though in fairness, a quick check of History also shows that the West has never been very 'kind' towards China either (think the Brit-inspired Opium Wars, the Boxer Rebellion, or how 'bout that time when Japan invaded China and murdered millions... while the West just stood by and 'watched'). So they have a lotta reasons not to 'trust' us too.

I believe this is true with current patent laws. I do know some items are as a little as 7 (pharmaceuticals) and others are ten with the option to renew for an additional ten. From what I understand the patent laws changed in 1952 and again 2005-2009

Just checked the Trademark database. Man do I have the subject for a new video! Hint- well yes and no!
