Our handmade wooden, cutter guide allows our Heavy Duty Cutter Blade to slide snugly down slicing your soap logs into uniform, professional looking bars. Takes up to a 2kg log of soap, both Melt & Pour and Cold Processed Soap.Soapers are making harder soap! The Heavy Duty Blade is not flexible and so is able to cut harder soap without any bowing. This is a modified guide to suit the Heavy Duty Cutter Blade. Suitable for Soap Logs Made in our Wooden Log Mould as well as soap made in milk carton soap. Internal width takes a log up to 100mm in diameter - sides of the guide measure 70mm. Alternatively, you can flip the log on its side if its wider than this and slice on its side. To achieve straight slices, pressure must be applied from directly above the blade - as you bend the blade by leaning at an angle. Soap should be as fresh as possible, the harder the bar, the mould difficult to cut. Not suitable for Crinkle Cutter or our Rounded Loaf Mould
