I'm sort of ambivalent regarding the grip ring (some people seem to not like it) but I did order some spacer rings which can be used on either the TK12 or TK15 if you replace the grip ring.

我有点矛盾对于抓地力环(有些人似乎不喜欢它)，但我却订购一些间隔环可用于对或TK 12或TK 15如果你更换握把戒指。

Like the TK12, the TK15 comes with both a pocket clip and "cigar grip ring" which allows a better grip when holding the flashlight like cigar or plunger - both the clip and grip ring can be removed.

喜欢TK12 TK 15来，一种与口袋里夹和“雪茄抓地力圈”，它允许一个更好的控制当拿着手电筒喜欢雪茄或顶针控制包括夹和戒指可以去掉。

This grip is working with ring crush tester to test the column compression strength.
