Hi Daxx.
I use oils available from a UK firm called Colron, they are excellent. I looked for a site on the net that you could find them but was only able to come up with a hardware shop
in the UK. Probably stuff like this isn't shippable by post to the States, but have a browse, see if you like the cut of their jib, and email me. I will obtain it and send it. Personally, I've used tung oil to bring up colours and pattern of grain on knife handles, no problems with performance, slipping etc. Boiled linseed oil is excellent, but I find it produces a glaze-like finish, I don't think (personally) you want that on a khurkuri handle. If you do a search for 'Bussen & Parkin' you will find a dumb site, but they do Colron stuff. You need to decide what you want, obviously. I've used the Danish oil and the Antique oil to finish furniture that I've built, but again they produce a glaze-effect. Once you have oiled a handle, it isn't going to take another finish! Please avoid edible oils, they are no good and will ruin your khuk! If you want to see how the finish would look on the handle, lightly dab on some metholated spirit, which will wet the wood and bring up the colour/pattern and then evaporate without damaging the wood. As with your other respondents, I urge you to use an open, well ventilated area as these types of oils oxydise and produce harmful gasses. Destroy rags/paper and so on in a fire outside afterwards, because they can sponteniously combust due to the heat producing oxydisation process. Or, better still, send me air fare - I will bring everything, do it, and have a good old holiday.
Dave
