"MACKENZIE'S" PATENT, 



RUBBER TAPPING KNIFE. 



Rubber Planters are asked to note the chief features 

 of this Invention. 



(1) Two movable guide blades actuated 



by screws in such a manner that the 

 depth of the cut can be regulated to 

 an exceeding fineness . 



(2) Independent movement of these guide 



blades so that they can be set to 

 guide the knife w hen cutting on un- 

 even surfaces . 



(3) The guide blades are so arranged that 



either can be l owered at will and the 

 knife is therefore cha n ged from an 

 incisor to shaving knife to cut either 



right or lett hand as desired 



Experience has taught us that the "Mackenzie" Knife 



not only dees better aork than any other at present 



in use in Ceylon or the Straits, but that it enables 



the most Unskilled Codies to do it in jrom 



l-5tli to 1-1 Oth the time formerly required. 



Price Rs. 500 each.
