. Introduction to botany. Botany. be obtained in section cutting witiiout sliarp Icnives and razors. An oil- stone should therefore be provided, and a fine hone and strop for razors.^ To sharpen an ordinary pocket knife, hold the under face of the blade at an angle of about ten degrees with the stone, and impart a sliding back and forth motion, honing the two sides alternately until a keen edge is produced, keeping ' â ., the stone well oiled "^^^^^^^ with mineral oil. The razor should be kept in such con- dition that at any place on its edge it will readily cut in two a hair held be- tween the thumb and forefinger. If it will not do this, it may only need stropping on the prepared leather of the strop. To tell whether it should be honed on the stone before stropping, moisten the ball of the thumb and pass it with gentle pressure longitudinally along the edge of the razor; if the edge, throughout its length, produces the sensation of tak- ing hold of the skin, the use of the stone will not be necessary, but otherwise the razor should be honed on the oil- stone until it re- sponds properly to the test. In honing, oil the stone with mineral oil; hold the blade of the razor flat on the stone and slide it edge foremost along the fiill length of the stone, imparting a longitudi- nal as well as a forward motion to the razor, so that it glides for its fall length from point to heel over the stone, as shown in Fig. 203. Then turn the razor on its back, so that the other side lies on the stone, and slide the razor forward and longitudinally, edge foremost, as before. 1 One of the best for this purpose is the Torrey combination strop and Fig. 204.
