Japanese manufactured set likely ca 1960-70s. I suspect they are very good quality and they came from the workshop of a serious woodworker and have sharp edges ready to work. 1/4", 1/2", 3/4" and 1" bevel edge chisels. Very similar to Marples blue chip set and branded for Canadian Tire who for many years sold some good quality tool brands.
**All edge tools may need to be sharpened/honed before use**
