This study haa raa1tioat1one beyond the material dea1gn, developmen�, and aanutactur• ot a tool gr1nd1ng t1xture. attapt to gain add1t1onal per90nal skill, An depth 1 creat1Y1ty •- and und.ers,and.1ng in the areas ot m&ch1ne metalworking techn1 c·al dratting were sought am and aehieved by the writer. Furthermore, 1t 1s conceivable that this type ot atudy or tho•• ot a •1•1lar nature could set a preoeden� 1n ad.Tarioed. 1nduatr1al arts courses on the secondary lnela to turther re1ntoree the bond and ooll•s• ot understanding betwe9n er aore r.iated 1ndustr1al twe areas. It is th1• writer'• op1n1on that industrial art• eduoatora have OTeJ'looked. to so•• degree in teaoh1ng, the relationship of one 1nduatr1a1 aubjeot aatter area to another, thus creating a tn total conceptual under vo14 standing. a111p11f1ed nudy or exero1•e of thle nature A oould be incorporated lnto 1nduatr1al arts oour8• work to further strengthen •tuden.t ubd.ernand1ng of the total concept of 1nduatrr.

It was established e that a need existed pertaining to the accurate sh ening arp of bevel-edge blades and knives of the type used 1n wood surf��inE.� tools, spec1f1cally plane iron blades, Jointer knives� surfaoe planer knives, spokeshave blades, straight router cutters, straight shaper blades, flat shaper knives, straieht wing outters, and flat scraper blades. Existing methods of sharpening these blades and kn1ves been 11m1ted primarily to the utilization of have pedestel grinders and relatively crude unsoph1st1oated and jigs fixtures. Not only are these methods in ccurate, end a but eonsiderable danger is involved to observers mid the operator using these devices due to possible improper or careless construction. These contemporary methods of grinding are often laborious in e.dd1t1on to being inaccurate. The very inaccuracy inherent in these methods would ind icate laboriousness since trial and error methods ot alignment, 2 gr1nd.1ng, and ••aaur•ent or ancl•• employ .
