10-18.104.22.168 Use a smooth cut file and finish with a sharpening stone. Never grind with an
emery wheel, as this takes the temper out of the metal.
10-22.214.171.124 The outer ridge of the gaff must never be filed. To obtain the proper width, a
file may be used on the rounded portion. Apply strokes that follow the contour of the
10-126.96.36.199 To sharpen the gaff to proper thickness, file the metal from the flat inner side
of the gaff. Care must be taken to prevent notching the leg irons or stirrup. Use forward
motions toward the point and down to edges of the underside of the gaff. Do not allow
rocking motions of the file because this can round the edges of the gaff. After the
proper thickness has been reached, the underside of the gaff must be straight to within
1/16 in (1.6 mm) of the point, then rounded slightly toward the ridge of the gaff on a
radius of 1/4 in (6.4 mm). Additional sharpness may be obtained following filing by
dressing the underside and rounded portion of the tip with the honing stone. Burrs
along the edges must also be removed with the stone.
10-188.8.131.52 Never use a climber with a gaff shorter than 1-1/4 in (32 mm), as measured
on the flat side.
10-5.2.7 Restore damaged or dull gaffs to original shape (see Figure 10-3) by filing
and honing (see Figure 10-4). If gaffs cannot be restored, replace them.
