I made a few knives recently my best friend and her fiance.
L's a stay at home mum with a shoemaking background and general creative and artistic flair so I thought a utility/craft knife would be suitable. I wanted to make a wharncliffe style blade with a hidden tang for a left hander.
I made the blade out of the other end of the file I used for SBW's knife and the handle is nickel silver, tin, reconstituted stone, black and white spacer material and curly birch finished with Danish oil.
S is a whiz in the kitchen so a chef knife was the obvious choice - or at least obvious after asking L for ideas and having her suggest it. I freely admit that I cheated with this knife and actually bought the blade as a blank, rather than grinding it myself. I was concerned that I'd grind too much off making such a thin knife and simply didn't want to take the chance. So rather than this being a custom knife it's more of a 'customised handle' knife, as all I had to do was fit a handle and give the blade a bit of a quick sharpen and strop.
The blade is a 440c stainless Santuko that I purchased from Jantz Supply in the US. Handle is made from red spacer material and Fiddleback Redgum. I finished it with a few coats of danish oil and sealed with wax.
