Sharpening a new skiving knife

Recommended Posts

I've just bought a CS Osborne No 479 skiving knife and would like some advice on how to go about sharpening it.

I don't yet have any stones or guides, but have the items listed in THIS video added to my amazon shopping list, just in case. Don't think the chisel honing guide is going to suitable though.

I've watched that video, and IMO it's more complicated and involved than you need

I haven't used your knife, or any other Osborne tools, but I would expect that a knife from such a reputable maker would be more or less ready for use (though I'm willing to be corrected). All you need is a fine stone and a strop. The stone can be any type you want - 

Oil - Not as popular (fashionable?) as they were, but they do the job. Fairly cheap to buy, but because they've been around for so long you can find them secondhand. See if there's a second hand tool stall on your local market. Just ask the stall holder, they're friendly enough. Ordinary general purpose oil like 3-in-1 is OK

Diamond - Probably the easiest to use. Good ones are expensive

Water aka ceramic - A bit messy. You can get various combinations with different grades & prices

Make your own strop from oddments, it's just about the easiest bit of leatherwork you'll ever do Take a piece of wood about 12" X 3", though it doesn't need to be precision carpentry by any means. Cut a piece of 2 to 3mm veg tanned leather slightly oversize

Place the leather flesh side down on the bench (so you're gluing the grain side to the wood); apply glue to the leather and/or the wood; general glue like Bostik or UHU, or PVA wood glue is OK; place the wood onto the leather and weight it down - a few books, or a small toolbox, or a couple of saucepans of water. Leave it overnight to set. Next day trim the leather to the wood. Treat yourself to some proper stropping /honing compound, I use Veritas 05M08.01 from Axminster Tools. A 170g bar will last you for ages

It will take a while to break in the strop. When the colour changes to black you know it's working because that is the steel that's being removed from the blade

There are loads of sharpening videos on YouTube. Play around with the Search box for sharpening knives; using  an oilstone etc; making, & using a strop. Watch as many as you have the stamina for, you'll see how things are done, how they're used, and work out your own technique

Hmm, I'll keep those in mind, especially the one about sharpening videos online. Thanks!

fine stone

I picked up a great Arkansas stone from a secondhand tool shop for £5 UK / $6.60 US, so its well worth looking.

Never did get on with the new fangled, everything changes, diamond stones (even Mrs HW did not want one as a mothers day gift - I told her it was diamonds and everything!)

The comments on a strop are spot on too. Mine has two flesh sides (one each side) one with a carborundum mix, home done, the other is just Flesh side out, but very tight horsehide, as a final polish.

How is your sharpening coming along? Sorry I'm so long in replying.

Give us an update and I'll do my best to post whatever help I can. The folks here have helped me so much I feel guilty not paying it forward.

What sharpening supplies do you have on hand now, and what is your budget for sharpening stuff? (Like "minimal", "I'll buy stones, but keep it cheap," "Hey, let's make a hobby out of learning to sharpen everything in the house!" )  The latter is what I did and no looking back. I've passed on those skills to all 3 of my kids, along with stones and knives. Now I get lecured when my kitchen knives are not up to snuff.
