Do you go with the black resin handles or polished aluminium? There is of course no wrong answer and it will be very much be driven by personal opinion (we currently have a mix).
Rada knives originally came with the polished Aluminium handles - a beautiful finish which looks like no other knife and is extremely durable. However, when washed in a modern dishwasher the combination of aggressive detergents and high temperature oxidises the aluminium surface resulting in the handle becoming grey (even after several washes). This will not affect their performance - just the appearance.
The resin handles were introduced as an option for consumers who do wash their knives and kitchen cutlery in a dishwasher (although this is not ideal for the blade). The resin is also extremely durable and far superior to plastic or rubber handles. The texture ensures greasy hands will not slip.
The resin handles are the same physical dimensions but make the knives about 5 - 10% lighter. Unlike a metal handle they do not transmit heat so will never be hot or cold when held.
The resin used is extremely tough and should not be mistaken for plastic - unlike plastic, resin does not get brittle over time or soft at high temperatures. It is an extremely tough material and is perfect for knife handles.
On the end of the resin handles, you can see where it was poured into the mould - each knife being very slightly different - we like it, as it gives each knife a bit of its own personality.
Overall the choice is very much a personal one - both are elegant and both materials have passed the test of time. The aluminium handles just need extra care to ensure they remain beautiful.
Also, worth noting is that the Resin Handles match on both the knives and utensils giving you the chance to have a consistent presentation across all your kitchen cutlery.
This probably sums up the key points.
We have chosen to support the Rada's utensils in only the Resin Handles - the reason being that we believe that this type of kitchen cutlery will often be put in the dishwasher and the durable resin handles are a better fit (although we can order in the Aluminium if you wish).
