Figure 105. Fanning Island bonito hook points, western type. a, perfect point: base with slight proximal prolongation (1) to enable two holes to be pierced through base; curvatures of hook ground on either side to sharp edge; grinding on lesser curvature comes down on line of proximal hole (2) which would be seriously weakened but for proximal prolongation (1); length of base, 24 mm.; distance from point to distal end of base, 63 mm. b, perfect point: marked proximal prolongation (1) increasing…
Figure 105. Fanning Island bonito hook points, western type. a, perfect point: base with slight proximal prolongation (1) to enable two holes to be pierced through base; curvatures of hook ground on either side to sharp edge; grinding on lesser curvature comes down on line of proximal hole (2) which would be seriously weakened but for proximal prolongation (1); length of base, 24 mm.; distance from point to distal end of base, 63 mm. b, perfect point: marked proximal prolongation (1) increasing length of base to 22 mm.; proximal hole bored through prolongation; distance from point to distal end of base, 53 mm. c, broken point: marked proximal prolongation (1) making base 31 mm. long; diameter of large holes, 6 mm.; depth of prolongation, 14 mm.
