a first ram comprising: a base section; an upper blade section, a plurality of interlocking arms extending along the upper blade section and forming interlocking channels between the upper blade section and the plurality of interlocking arms, and a first set of anti-deflection features formed in the plurality of interlocking arms,
wherein the upper blade section and the plurality of interlocking arms protrude from the base section in a first direction, and extend along a longitudinal axis, and
wherein an end face of the upper blade section and a respective end face of the plurality of interlocking arms at least partially form an end portion of the first ram; and
a second ram comprising a lower blade section, a plurality of interlocking tabs extending from the lower blade section, and a second set of anti-deflection features formed within the lower blade section, the second set of anti-deflection features extending from an end face of the lower blade section and along the longitudinal axis, wherein the plurality of interlocking tabs is configured to extend into and translate along the interlocking channels to enable the first set of anti-deflection features to engage with the second set of anti-deflection features.
