Knife advice

Like the secateurs idea. Do they come in dyneema cutting grades?

One for our Dyneema cutting correspondent @Seaworthy Lass...?

As we talk about knives for specific tasks, I found this one very good for any underwater emergency work, example fishing lines, nets or ropes around the propeller: when diving to cut something, one has to hold with one hand to the shaft/propeller while using the other hand in the opposing direction to cut the rope, the boat is often moving so there is the risk of cutting one's hand; with this hooked knife one simply grabs and pulls, grabs and pulls...

See my earlier post. Had mine issued to me in 1990 , still use it, I think it will last forever

I got a non serrated Wichard knife from Decathlon - from memory it was about £8. Fantastic piece of kit.

You got a VERY good price - they're at least £30 now. And none of the current range have marlinpsikes , and those that have shackle keys are all serrated blades.

Even the pusser’s dirks are now over thirty quid.

I like the idea on the one I linked to in #22 of cutting a shackle key into the blade.

In a spirit of enquiry, I have just taken the household secateurs to some Dyneema.

It laughed.?

I just checked, it seems the correct English term is "line cutter", googling "diving line cutter" gives a lot of similar types.

That particular one on Amazon US
Amazon.com : New Safety and Rescue Scuba Diver 7.5 Inch Line Cutter with Cordura Sheath - International Rescue Orange : Divers Knives And Shears : Sports & Outdoors

The stubby ones like these below are being provided with some of the more recent lifejackets, to cut the tether in an emergency; they are about 10-12cm long.

I once left the boat for 6 months in quite warm waters, when back I discovered the propeller had caught a small fishing net, around which had grown a giant ball of mussels which hid the whole propeller: a pair of gloves and one of those knives, poke and pull, poke and pull I eventually got rid of everything.

Just for interest, and having had a little more to drink than usual, I tried shaving with the Camillus knife. I can state that even with my rather strong stubble, it is shaving sharp!

I'm late into this discussion but I'm also of the era when every small boy had a penknife in their pocket - I still have the bone-handled classic two bladed folding 'penknife' that I was given when I was 8 years old.

I'm also a scout leader and teach axe, saw and knife safety to 11 and 12 year olds. They also use knives in cooking their own meals on a fire. I can't think of any other way or organisation, these days, that will teach young people to use such tools. It's unfortunate that a knife is now considered foremost a weapon, rather than a tool (unless it's in the kitchen drawer).

On a related note, if you want a completely rust-proof knife that can be immersed in salt water forever, look at the Spyderco Salt range, which uses a nitrogen rather than carbon steel. Not cheap though
