As an addition, but not an alternative, you can very carefuly apply some muriatic acid in strategic spots or a single spot depending on the look you are going for. Use caution if you opt for this. Also, I would suggest gently destressing the wood to match the look of the steel. Finally, for that ultimate aged look, you can hand rub the stain finish of choice with cheese cloth between appplications paying particular attention to places where hands would normally wear agianst wood and add a small bit of hardwood ash to to the stain or boiled linseed oil beween coats. A few applications of a good wax, again having a bit of ash in it for texture, to the wood will help with the aged look as it will collect in naturally occurring low spots in the stock. I used this wood ash addition to stain linseed oil and wax technique many times on furnature. It is important to practice on a scrap piece of similar wood to perfect the technique. Go slow and be paient it is a long process.
