A NEW TAPPING KNIFE. 
Mr. Leslie Badclyffe in conjunction with Mr. Holman 
Hunt has brought out a new rubber tapping knife, the 
■‘Quicksure.” It seems from the advertisement to be 
somewhat on the lines of the ordinary tapping knife, far- 
rier’s knife modified, but instead of having only one cutting 
edge, it lias a double one on each side making four cutting 
edges. The price is 5 shillings apiece or 52 shillings a 
dozen. They can be procured at L. Badclyffe & Co., 35 
Queen Victoria Street, London or C. Holman Hunt c/o 
Chartered Bank Kwala Lumpur.
