Will this hacksaw design work?
Would any one buy this hacksaw ?
So far I was able to list these benefits:
1) In my machine there are two springs to supply with enough pressing for easier cutting.
2) My machine has two blades to cut from both sides at the same time for faster cutting.
3) The blades in my machine are closed solving the problem of a loose hacksaw and causing cutting to be straight forward.
4) It is easy to use and can be used by anyone ; there is not a need for an  expert to cut straight forward.
5) The time the two blades last before replacement is double the time is needed for an ordinary hacksaw;we have two blades and they share cutting.
6) Using my hacksaw we can focus on moving the hacksaw and neglecting pressing; this will enable us to cut with faster speeds.

I think it will require more skill to operate a two bladed device than one with a single blade I cannot visualise me buying such a machine

1. Two blades would increase the force needed for each stroke, give less control
2. The blades would be pressing down during the back stroke, which is bad technique for using a hack saw, and would increase the amount of effort needed to use it, making it more tiring to use.
3. The two blade system would make it less versatile than a normal hack saw, meaning you would still need a regular one for those jobs for which it is not suited.

Also the wastage due to kerf width would be greater without any benefit.

The pressure you would need to apply to the bottom blade would either make the bottom blade useless, or a jam, sawing is not as simple as pushing a blade through, correct angle and pressure has to be achieved.
