I have another couple…
Shy - Opposite of Proud (See above) Not Flush.
Spall - See Tear-out above.
Gall - Smeared melty metal stuck to a cutting tool.
Strangle (A tool) Most usually a hammer - To hold it by the middle rather than by the end as the designer of the tool intended. Generally a result of a lack of confidence.
Arris - The sharp edge where two surfaces meet. Best removed for safety unless there is a compelling reason to retain it.
