Knife Sharpening

Recommended Posts

Brown Dog,

 

This new topic is very much in keeping with what we do in our spare time and I am sure people will have a lot to share and discuss.

 

I went stalking with some friends last weekends and when the subject of sharp knives came up, one of the guides, Ken, produced a hand-made knife that he sharpens using a strop. I have never seen anything like it and I learnt that the process also polishes the blade. What are your experiences with a sharpening strop and which ones you use, as well as compounds?

 

Regards,

 

George

 

I've lots to learn about sharpening knives well - anyone able to pipe-up on this with tips / techniques?

i'm ok with sharpening knives but would like to improve

 

my next step after using the diamond imprenated boards is to get a strop,,my understanding is that this is your last process as the grit value would be really high.you can do it like a barber this will give you a slightly rounded final edge or put the leather flat on the table and keep the same angle you have used with your stone etc.you can also use some type of paste to aid sharpening .if you dont let your edge dull then you could strop most of the time i guess.i have tried it a bit with a leather belt ,i does improve the sharpness even if its just removing the tiny burr that you get when sharpening

 

anyway thats my understanding ,some may know more.

Hi Matt,

 

I've just posted about knife sharpening on the Bushcraft sub-forum, perhaps BD would like to amalgamate the threads?

I have tried most sharpening meathods over the years and I have found the most efficiant and effective way to get a razor edge is the chef's choice 120.

Dave - just googled that - 200 quid?! blimey!

 

 

Like spud, I've got a Lansky - works but I'd like to do it with less kit. Also got a pocket size crossed ceramic rod thingy - that's what I use most.

 

But neither leave me feeling like they're a 'man of the mountains' solution :rolleyes::lol:

Have a search on the Net on this.

I ran across a very good series by an American guy who owns a big knife shop. He had a series of ??8 different video clips showing the A-Z of knife sharpening. I emulated what he did and now have most of my hunting and kitchen knives I'd rate as "definitely sharp" as opposed to the previous "so-so sharp"

 

Now if I could only convince my wife to give away those damn PE chopping boards- they bu**er the edge big time

If not much is around the bottom rough side of a porcelain plate or cup is not bad.

My favourite is a ceramic rod ~ 96% aluminiumoxide for the first step and then use

a dense silicon carbide sintered tube for the final bit. Never had good results with diamond although

we had a huge variety at my last work place.

I'm with Grant on this, Japanese waterstones are the way forwards....

Good morning,

 

knife sharpening is something that I have been studying for a couple of years now. I have Japanese waterstones, Lansky system, ceramic rods, diamond stones and the Spyderco Sharpmaker, as well as some leather strops that I have made myself.

 

Japanese waterstones are great, if one has the skill to use them. I found (thankfully on cheap knives!) that the variation in angle that is natural when moving one's hand back and forth eventually convexes the blade and, if not consistent, not in a symmetrical way. I have resolved that I need a lot more practice before I manage to have a symmetrical edge.

 

The Lansky system is great for maintaining symmetrical edges and is also quite capable to restoring the symmetry of blades (as you will need to do after ruining it whilst practicing with Japanese waterstones). However it is only good for angled edges (Scandi, beveled, secondary) and no good for convex edges (such as those in Svord, Bark River and Fallkniven knives).

 

I have achieved the best results with the Spyderco Sharpmaker. A simple system that maintains the angles that one nees for a razor sharp edge.

 

However, for restoration and maintainance of a sharp edge the only tool one needs is a good strop. I made mine from 2inch leather (an old leather belt will do, I bought some leather from Tandy Leather, off the internet), stuck with woodglue on a 2 inch wide, 10 inch long piece of oak plank. Apply some abrasive medium on it and keep stropping (abrasive media are things like Autosol, TruCut, toothpaste, brasso, or some soap-like material that you can buy specifically for the job. Heinie Heines and a range of other outdoor suppliers sell these), even after having just dressed a rabbit. It maintains the edge beautifully and polishes the blade.

 

Having a sharp knife is the only knife worth having (after all, if it ain't sharp, it's just a piece of metal), and to that end I spent countless hours studying how best to achieve this, although, by no stretch of the imagination am I an expert. What works for me is

- stropping only if the knive has had some use that was careful (i.e. not hitting bone or teeth when dealing with a carcass, not dinging the blade on rock or soil when working with wood etc)

 

- A few passes on the Spyderco Sharpmaker till the edge has been restored and then stropping to get a hair popping edge.

 

If you have convex edge knives, the best instruction on how to sharpen those comes from the videos on www.knivesshipfree.com. (http://www.knivesshipfree.com/pages.php?pID=4&CDpath=0)

 

- A rough-to-smooth work with the Lansky, then onto the Sharp maker and then strop, if there is a serious ding on the blade.

 

If I am out and about, I have a portable kit, which is a DC4 stone (made by Fallkniven) and a slice of dried razorstrop fungus (which you can collect yourselves from your trip to the woods, whenever you come across a dead silver birch tree). And that works great on the hill to restore your knife after gralloching your beast :)

 

That's just my limited experience and it would be interesting to see what regimes others use to maintain their knives.

 

best wishes,

Hi

 

I have bought all the different systems over the years, and now only use the Japanese Water stones and the frame for holding the stones.

 

I recon that for sheer cutting edge sharpness they are hard to beat.

 

I have a number of handmade knives, some in stainless and some in tool steel and they all take an excellent cutting edge using the water stones.

I have tried Lanksy, Gator and Smiths ceramic sticks over the years, but was advised by Alan Wood ages ago to use the Spyderco Triangle Sharpmaker , since when I have stayed with it for all stalking, woodcraft and kitchen knives. Easy to use, and produces a seriously sharp edge. Good advice from someone who knows his stuff with knife steels.

Never have any trouble sharpening knives I used to work in a slaughter house for ten years and when skinning animals all day you learn pretty well what gets then sharp and more importantly what keeps them sharp for the longest. Normal Oil stone smooth side will plenty oil and we called them a steel at work. The ones you see in the chefs using in the cooking programs. These were really more important than the stone sharpening. Good steel,s were prized. I still have mine and use it for the household knives even though I left the trade years ago.

The knives actually took a while after sharpening to come to their sharpest. I have no problem running my knives down my arm and removing all the hair like a razor does.

As said above avoid teeth they dull it straight away. Avoid over sharpening and getting a folded edge these won't get really sharp. As for the point I found that the "tanto" style worked best for the purposes I needed as using different parts of the blade to do different jobs is also a good way to make the edge last longer. I used to use the heel of the blade nearest the handle for cutting through hide and dirt that accumulates on it on legs and then rip from the inside with the point for hide cutting over any distance.

I have a stone for rough spots, a Dick steel to roll the edge, and a square of 4mm leather to Polish the edge.

I can't shave with mine, but I can zip through a deer with ease and have not cut myself (touchwood) in years from forcing a Dull knife or being to close to a sharp one

I have tried them all, the ones that seem to do the job anyhow, not the 'v' shaped ikea gimics ! best i have used & still do, good old flat piece of Yorkshire sand stone, wet.thin the blade of your favourite tool, finish on a good steel. I worked in the abbatoir for years , everyone used it . The resuts are razor, once perfected.

Hi BD

 

I use leather strops only for sharpening my and my friends' knives. A 5-7 cm leather strip, about 25cm long is more than adequate for all needs. Glue it with wood glue on a similarly sized piece of wood, apply some compound (easy to find in all carpentry and knife websites) or autosol/trucut from halfords and you are good to go.

Place your blade flat on the leather and lift so the beveled edge is now flat with the leather surface. Drag the knife working from the base to the tip of the blade, at the end of the stroke turn the knife so the other side of the blade is now on contact and repeat 30-40 times.

I use stones etc only if the knife blade has had particularly hard use or shows nicks and flat spots.

Hope this helps

Kev T has the right idea a good steel is what you need to put a good edge on the blade after sharpening. They won't stand up to hard use but then what blade does. Easily blunted (don't touch teeth, grit or hard that which promotes growth and vigour on the carcase with any knife blade. Try working from inside the hide to the outside)Use the heel of the blade for initial cuts. Using an oil stone and a steel you won't get sharper for longer with them 15 years in a slaughterhouse proved that more than once. Problem is it takes years of slaughter house use (skinning and ripping open hides) to get the right angle, shape of point and which parts of the blade to use where on the carcase to get the edge to last any length of time. Thats another thing they were never their sharpest just after sharpening neither always took a half dozen beasts to get the edge to its best ( You only did a small part in the cattle on a large production line ie a leg, rumps or belly etc etc. One of the biggest secrets was the steel. If you get a good one hang on to it smoother is better and slow strokes with the knife when using it always worked best for me. I could sharpen my working knives and shave an arm with them once they got a good edge going no problem.
