握柄是由一種名為DynaFlex的合成防滑材料所製造,具有符合[[人因工程学|人體工程學]]的開槽,而且比圓形更[[椭圆]]。這種設計有助於在訓練時防止重複性緊張損傷和手部疲勞。它還具有海军陆战队标志的浮雕,讓使用者在黑暗中識別出刀片的方向。其[[莖 (器具部位)|全長度刀莖]]連接著平直護手片/槍口環(這是在4.19[[毫米]]/.165 [[英寸|英吋]])和用以緊扣著槍管刺刀座的柄端閂鎖板;兩者與刀片一樣都是具有磷酸鹽塗層。前安大略刀具公司總裁兼首席執行官尼克·布維治二世({{Lang-en|Nick Trbovich Jr.}})曾這樣說:「我們花了很多時間來確保握柄符合人體工程學是正確的……在手柄上並沒有起泡點。海軍陸戰隊員是最好的,他們應該得到最好的」。<ref>原文:“We spent a lot of time making sure the handle was ergonomically correct… There are no blister points on the handle.
