A side-push type composite putty knife which comprises a handle and a blade with a rear end of the blade inserted into a blade receiving slot at a front end of the handle. The rear end of the blade has a blade tang which is provided with a fixing notch on a side thereof. A lateral gliding slot which is in communication with the blade receiving slot is disposed at the front end of the handle inside its casing. A latch and a reset spring pressing against a first end of the latch are disposed inside the lateral gliding slot. A pressing part is formed by a second end of the latch which extends outwardly from a side of the casing at the front end of the handle. A pin is disposed at the first end of the latch which presses against the reset spring. When the blade tang is inserted into the blade receiving slot at the front end of the handle, the pin engages with the fixing notch of the blade tang. The engagement between the latch on the handle and the fixing notch on the blade allows the handle and the blade of the present invention to be removably assembled, and therefore fulfill the object of replacing blades of different specifications on the same handle. Cost of use will be lower accordingly and carrying the knives becomes more convenient.
