First of all, the cutting effect of wave knife is more beautiful. Because the incision of the wave knife is wavy, some decorations can be added to the surface of the handmade soap to make it more beautiful. Moreover, when using the wave knife to cut handmade soap, the design of the cutter head can make the cutting operation easier, because the wave shape reduces the friction force, reduces the requirements for hand force, and also avoids the risk of broken soap in the cutting process of handmade soap.
Secondly, the cutting effect of the straight knife is smoother. When cutting handmade soap with a straight knife, the incision is relatively flat and there is no wave shape, which makes the handmade soap more regular. Moreover, the design of the straight knife can make the cutting operation more simple and clear, because it only needs to cut in a straight line without special skills. In addition, the straight knife is smoother than the wave knife, which can reduce the appearance of residual traces on the surface of handmade soap.
On the whole, wave knife and straight knife have their own fields of expertise. If you want the surface of handmade soap to be more beautiful and not easy to break, then you can choose wave knife; If you want the handmade soap to be more regular and the incision smoother, you can choose a straight knife.
Of course, the final choice still depends on personal preferences and usage habits. If you think these two tools have their own advantages and don't know which one to choose, you can choose according to actual needs.
