I just want to mention that I cut perfect bread to whatever slice width I want with an old Philips Food Slicer ie. with a circular blade. Similar slicers are often cheaper than a good serrated bread knife (I looked on Amazon) and certainly cheaper than a bread knife and a slicer guide. The other day I did perfect 13mm wide slices and today I did standard 11mm width slices no problem at all and it looks like it came from a professional bread slicing machine from the bakery pretty much. Far better than I was doing with a knife and I’m not that bad with a knife either.
Just thought I’d throw that out there in case it helps…
I don’t mind a rustic slice of bread but I count my calories and it’s nice to have them consistent in terms of weight per slice sometimes.
A good slicer certainly adds to the bread baking experience. Recently I picked up a fifties manual German bread slicer for ten bucks. Gave it a good overhaul, cleaning and lubrication. Works like a charm!
Electric or manual, either way it is a must have tool.
