For my regular model work, I use an American X-ACTO design knife.However, I thought the design knives sold at Daiso were similar in shape, so I decided to buy one.
I took the opportunity to buy a design knife with 3 replacement blades from Seria.
As you can see from the shape of the spare blade, this design knife seems to be a special one, and it did not fit into the Daiso/X-ACTO grip.The reverse is also impossible.
So, it seems that Daiso's No. 115 and 116 can be used by swapping both the grip and blade with X-ACTO.How durable is it?(laughs)
Sorry if the information is not very useful (lol)
