bottle mouth insert and the rim of the bottle see fig2 the counterbore angle of the bevel in tapered embodiments may be between approximately 5 degrees and 12 degrees in some embodiments in which the tool 1 is formed from a particularly durable substance such as aluminum a bevel angle between about 7 9 degrees may be advantageous in some embodiments the bevel corners 34 may be rounded or angled to reduce any sharp projections around the edge of the tool 1 in the pictured embodiment the bevel or ledge 32 is cut down or recessed from one surface of the tool 1 turning now to fig2 there is shown a cutaway side view of the bottle cap pry and press tool 1 embodiment of fig1 n including the press opening 10 and press flange 12 as well as a cross section showing tapering of the shaped bevel 32 in the profile cutout not labeled in the present embodiment the shaped bevel 32 has a counterbore angle of approximately eight degrees this tapering of the bevel 32 may be formed by for example a u215d u2033 counterbore or end mill drilled into substantially the full curvature of the profile cutout 30 to a depth of approximately 0 2 cm one advantage of this relatively sharp angle is that the leading edge of the bevel 32 is sharper and may be more effective when prying very small bottle cap inserts out of very small bottles where a larger bottle cap insert must be pried out however a larger counterbore angle may be preferred for increased durability in order to match the design of other bottle cap inserts other.
