Rare, Early 1800's James Howarth Knife Sheffield England

Description

Rare Early 1800's James Howarth Carbon Steel Carving Knife Sheffield England
Early to mid 1800's carbon steel Carving knife made by James Howarth.  Blade shows very minor signs of rust or discoloration. The b
lade profile is out of alignment, not all that unexpected after 150+ years of use.
The handle has a smooth, warm patina and feels good in the hand.  The tang is solidly held in place by five pins and doesn't show the least bit of play or wobble, a definite testament to the quality workmanship and materials used back in a time when hand craftmanship and pride in your business was the norm.
While better known for making chisels and planes, Howarth did occasionally make some cutlery, but it is extremely scarce.  I have been checking ebay for over a year and there has never been another knife listed!  I also spent well over an hour Googling it and found no similar knives of any size or shape made by James Howarth.
Per the below history, this knife was likely made between 1842 and 1863
A quick history of the James Howarth company -
In 1834 James Howarth started his first business when he formed a partnership with Henry Taylor and established Taylor and Howarth making light edge tools for the next 9 years until it eventually dissolved in 1842.  Even so, James continued to make edged tools like wood planes, draw knives, etc), as well as hammers, squares, bevels, spokeshaves, gauges and more.  All were of exceptionally high quality and he even won First Prize medals at the London Exhibitions of 1851 and 1862 as well as Paris in 1855.  His goods were well sought after in Europe, Canada, Australia and even China. In 1863, the firm changed its name to James Howarth and Sons.
