The invention discloses a multifunctional cutter for laboratory cutting. The multifunctional cutter comprises a cutter head and a cutter handle. The cutter head comprises a cutter point, a cutting edge and a cutter back, the cutter handle comprises a handheld handle and a holding circular ring, the cutting edge comprises two upper cutting edge bodies and two lower cutting edge bodies, the lower cutting edge bodies serve as main cutter bodies, the upper cutting edge bodies serve as auxiliary cutter bodies, the upper cutting edge bodies and the lower cutting edge bodies are intersected at the cutter point, and a 22-degree included angle is formed. A buffering area is arranged on the cutter head and located at the position where the cutter head is connected with the handheld handle, and the holding circular ring is arranged at the tail end of the cutter handle. According to the multifunctional cutter, conventional cutter processing items in a laboratory are carried out with multiple effective solving modes such as cutting, paring, mowing, peeling and splitting, different processing modes and different cutting angles can be replaced according to practical requirements in the use process, demands of different working objects and different processing methods are met, and the multifunctional effect is achieved through the multifunctional cutter.
