Claim:
A handheld modular tool to cut and mark, said handheld device comprising: a) a cutter module having a first end and a second end, said cutter module having a cutter retained in said cutter module; b) a marker module having a first end and a second end and an externally accessible through-aperture in a sidewall of said marker module, said marker module having a marker; c) a coupling element having i) a first end, ii) a second end, iii) an interior portion between said first end and said second end, said interior portion thicker than said first end and said second end of said coupling element, iv) said second end comprising a spring-tab arm extending from said second end of said coupling element and terminating in a spring-tab, v) said first end of said coupling element comprising a friction-fitting end structured and arranged to friction-fit into said second end of said cutter module and to linearly slidably engage said second end of said cutter module, without threading or applying torque or twisting to said cutter module, to sheath said first end of said coupling element and wherein said second end of said cutter module abuts said interior portion of said coupling element, vi) said second end of said coupling element structured and arranged to linearly slidably engage said second end of said marker module, without threading or applying torque or twisting to said marker module, to sheath said second end of said coupling element and wherein said second end of said marker module abuts said interior portion of said coupling element, and vii) said spring-tab of said spring-tab arm also structured and arranged to engage said externally accessible through-aperture of said marker module and, when engaged, said spring-tab is externally accessible; and d) wherein said marker module cannot be disengaged from said coupling element until said spring-tab engaged with said externally accessible through-aperture of said marker module is displaced from said externally accessible through-aperture of said marker module.
