Timber Defects
Wood Warping
- To understand why such defects occurs needs an understanding of tree growth, conversation of the lumber (timber), and seasoning. 'Warping' as such is a generic term for some of the defects caused by some irregularity or problem during the growth, conversion and seasoning plus eventual storage.

The various warping categories listed in Wood warping are also defects and should be included in this article.
Warping is a defect caused by a problem in conversion and seasoning of lumber (timber) and should not be treated separately.

Oilstones
Most whetstones are lubricated by using various types of oils and water.
It is not particularly for the benefit of the iron but for the stone.
An iron being honed on a stone or other abrasive device creates particles of iron and abrasive which clog the pores of the stone and thus 'slows' down the process.
Perhaps a single iron being honed on a clean dry stone may produce a good edge but the condition of the stone will not be fit for another session without extensive and perhaps difficult cleaning.
Using a light oil provides a fast edge which is rabidly absorbed into the stone, and heavier oils are slower cutting but provides a more durable surface to suspend the debris.
Water is just another type of lubricant but requires the stone to be held in a special made water trough as a reservoir.
